Riverbed announces RiOS 6.1 update for Steelhead appliances

A big day today in technology news. On the consumer side, Apple will be unveiling their new gadgets during their worldwide developer conference in San Francisco.

Not to be outdone, Riverbed is generating excitement today in the IT landscape with the launch of the RiOS 6.1, a hefty software update to Riverbed's award-winning Steelhead appliance.

RiOS 6.1 has new optimizations for Microsoft applications like Exchange 2010 and Microsoft Online Services and storage optimizations for SRDF and FCIP. There is HA support for RSP. With this release Riverbed delivers superior acceleration across a wide variety of infrastructure, thereby providing maximum performance for any cloud, architecture or application.

Riverbed is announcing a lot of Industry Firsts with this software update.

With RiOS 6.1, Riverbed is the first WAN Optimization vendor to offer optimizations for the following:

• Microsoft Exchange Server 2010(Encrypted and Unencrypted Mode
• Microsoft SharePoint 2010
• Microsoft Online Services (Exchange Online and SharePoint Online)
• SVVP Certified for Windows Server 2008 R2
• Lotus Notes 8.5
• EMC SRDF/A Optimization (Network and Application layer) and auto-configuration

Microsoft Optimizations
Accelerating Microsoft Applications from wherever they are located. With this release, customers running Exchange 2010 can see data reductions of up to 95% and more than 34 times faster transmission thereby reducing the effects of latency. There are enhanced optimizations for Share Point that further reduces the effects of latency and speeds up response time by up to 50% over previous versions of RiOS.
This release also provides support for optimizing Microsoft Online services aka Microsoft BPOS-D like Exchange Online and Share Point Online. The optimizations work in both encrypted and unencrypted environments for Exchange 2010 and Exchange Online.

Lotus Notes Optimizations
Enhanced support for optimizing Lotus Notes v8.5. For those customers with Lotus Domino and Notes environments, RiOS 6.1 delivers latency optimizations and improved application response times thereby improving the end user experience.
Storage Optimizations

Accelerating replication and DR traffic – enabling higher levels of data reduction and throughput
Customers that use EMC's Symmetrix V-MAX and DMX will benefit from a higher data reduction and better throughput due to the SRDF optimizations in this release. This release supports "auto-disable compression" for SRDF/A allowing for even better optimization for EMC environments. This release also provides FCIP optimizations and is certified and qualified with Brocade 7500 and Cisco MDS gateways.

Riverbed Services Platform (RSP) High Availability
Improved support for RSP in HA environments. RSP has been deployed successfully as a branch office box (BOB) solution across a wide array of customers. HA support for RSP allows customers the flexibility to consolidate branch office services without impacting availability.

Improved Network Resiliency
Added support in WCCP environments. With this release Riverbed is providing added support for multiple interfaces on the Steelhead appliance to participate in WCCP groups on one or more routers. This enables two use cases - load balancing traffic across multiple interfaces and fail-over to a secondary interface when the primary interface fails.

Central Management Console
RSP Management via CMCs. The CMC now can streamline the deployment and configuration of RSP and RSP packages. The new UI shows per-appliance health and status of RSP service and individual packages. Also there is now support for up to 2,000 Steelhead appliances managed by a single CMC

For me personally, the one issue I have with this software update is why is it named "6.1". Sure feels like a 7.0 update!  Riverbed customers have access this this software update by going to support.riverbed.com.

It’s (still) not just about bandwidth

It’s interesting to see how much has changed in the WAN (Wide Area Network) optimisation space over the last half a decade or more, yet some things haven’t changed much. Five years ago I recall a white paper had been written on the subject titled, “It’s not just about bandwidth”. At the time bandwidth reduction was a great story and the management reports within Steelhead were great at sharing how much bandwidth had been saved, but although some organisations were able to justify the business case on bandwidth alone many struggled. Saving bandwidth which gives rise to potential cost savings or as in most cases, defers bandwidth upgrades, is only part of the story and for most, a small part of the story. The real deal only happens as we speed up data across the WAN through either optimising the transport layer or better still accelerating the applications.

Now for some readers, this may not be anything new, it’s the bread and butter or simply put the basics of good solid WAN optimisation. But each week I am faced with questions from prospects & some journalists; with the advent of fibre everywhere, surely WAN optimisation struggles to add value right? Wrong!

Admittedly, if we run dark fibre from point A to point B over a relatively short distance and we connect our IT equipment at each end, with no service provider equipment in between then yes, WAN optimisation does not necessarily have a part. Bandwidth may be in plentiful supply but, more importantly, the biggest barrier to success across the WAN is latency and with dark fibre over a relative short distance the latency will be extremely low.

Today a number of service providers are upgrading their network to fibre only, offering much higher bandwidth options, in some cases up to 100Mbps and doing so cost effectively. This is great news for consumers and businesses, there’s no question about that but even with the almighty increase in bandwidth the latencies don’t go away over night. So if the issue is the speed of light, will increasing the bandwidth make the speed of light go faster? In short, no, as it still faces the same problems it did before. We can carry more traffic, hold more video conversations make more voice over IP calls and transfer larger files, but nothing goes any faster until we resolve the latency issue.

I recall a quote from Steve McCann, CTO of Riverbed Technology that was something like “The only way to overcome the speed of light is to not make the trip in the first place”. And it stands true today, more bandwidth is good, but once any bottlenecks have been overcome through either more bandwidth or a more efficient use of bandwidth the only way to make things go faster across your WAN is to optimise traffic leveraging technology such as the Riverbed optimisation system (RIOS).

So the idea that new fibre networks from service providers will provide more bandwidth is great, and I am sure technology development will improve for many, many years to come and continuingly increase in the phenomenon of more available bandwidth. But there is as much today as there was at the beginning of Riverbed and will be for many, many years to come a place for WAN optimisation technology as part of any IT infrastructure build to accelerate the data transferred across the WAN.

What do you think?

WAN Optimization, Security, and the Federal Market

For the typical enterprise customer, selecting a WAN optimization vendor usually starts with identifying solutions that do a good job accelerating the applications they care about, are scalable, and can be seamlessly deployed within their IT infrastructure.  For the government customer, there is arguably an even more important consideration that goes above and beyond speed, scalability, and simplicity and that is security.  There are 3 key security considerations for government organizations selecting a WAN optimization vendor.

1.  The existing secure infrastructure must not be weakened

Features need to be in place that ensure that as WAN optimization devices and/or software is deployed, additional security risks are not introduced. 

For example, Riverbed offers the ability to SSL encrypt the traffic between Steelhead appliances.  In addition to encrypting the traffic in flight over the WAN, Riverbed also offers the ability to encrypt the chunked data that is stored on the Steelhead appliance for optimization.  Up to 256 bit AES is supported.  The result is that with Riverbed, you get an end-to-end WAN optimization solution that is secure.

2.  You must be able to accelerate secure applications

Federal organizations that have deployed web-based applications that are SSL-encrypted, have encrypted Exchange email, or have applied SMB-signing to their file sharing environment to prevent man-in-the-middle attacks are often forced to make the trade-off between application acceleration for security.  For many WAN optimization vendors, they will simply pass this traffic through unoptimized or worse, will ask the customer to turn off security so they can achieve acceleration.

Riverbed has done a tremendous amount of engineering work to optimize and accelerate these encrypted environments.  With Riverbed, Federal organizations don't have to turn off SSL encryption, Exchange encryption, or SMB signing.  You get to have your cake and eat it too.  Accelerate your applications, while maintaining a secure environment.

3.  Must comply with federal security standards

Large government organizations, civilian agencies, and militaries deploy IT equipment that runs on networks, in data centers, in office buildings, and even in tents or vehicles to support a military endeavors.  This equipment must not only be secure, but it must comply with federal security standards including FIPS, Common Criteria, and JITC.  These federal security standard requirements are often extended to WAN optimization devices as well.

Riverbed has invested a large amount of resources to ensure that our products meet these Federal security standards.

If you are interested in finding out more about how Riverbed has been selected by government agencies around the world to accelerate applications, optimize bandwidth, consolidate IT infrastructure, and optimize disaster recovery, while doing it securely, please drop me an email.

5 things to look for when choosing a WAN optimization vendor

I recently blogged about the ABCD's of WAN optimization in an attempt to simplify the understanding of how this technology adds value to IT organizations.  After hopefully gaining a better understanding of WAN optimization, the obvious next step is to choose which WAN optimization vendor's product to deploy.  As Riverbed's evangelist, I am obviously biased, but I thought I would plot out what I see as the 5 key things to look for when selecting a WAN optimization vendor.

1.  Customer and industry recognition

Customer references remain king regardless of the product, technology, or service.  We see this with social media platforms like Yelp where the community shares their experience with a variety of businesses.  If a large percentage of the community rates the business highly, then there is a better chance that your experience will be positive as well.  The same holds true for WAN optimization.  Ask your vendor candidates to provide several customers that you can call to ask how their experience has been.  Even better, ask for references that represent an environment similar to your own.  Be wary of vendors that only have a small amount of references or simply provide you with case studies in lieu of someone that can accept a phone call.

In addition to customers, talk to industry experts to get their take.  For example, Gartner is one of the premiere analysts that covers the WAN optimization market.  They publish a Magic Quadrant spotlighting leaders and visionaries in this market.  These industry experts have done their homework and while their opinion is at the end of the day, just an opinion, it is an expert opinion.

2.  Proven ROI

Value and return on investment is cornerstone to any technology deployed in today's economic landscape.  Ask each vendor to go through an ROI exercise based on your environment in order to determine what the potential savings would be.  While the product cost varies from vendor to vendor, so does the ROI once you figure in the deployment costs, optimization results, and cost of the product as well.  It is also a good idea to ask for both customer and 3rd party ROI validation.  Beware of products that are considerably less as the old adage "you get what you paid for" often applies.

3.  Speed, Scalability, Simplicity

At the end of the day, it's usually about speed\acceleration\optimization.  How much acceleration do you get with each WAN optimization vendor?  Many vendors will tout acceleration for varying applications, but vendors differ in their implementation.  Look for vendors that have developed acceleration techniques geared towards mitigating the latency impact on the performance for your specific application. 

WAN optimization encompasses IT infrastructure technology that is often deployed as an appliances (hardware/virtual) at a branch office and data center and software that is deployed in mobile worker's laptops.  Scalability of this IT infrastructure as far as being able to address the demands of your user, network, and application loads is critical for very large deployments where there are large amounts of users and branch offices.  Being able to scale down can be very critical as well.  If you have small offices with only a handful of users, does the WAN optimization vendor offer a product specifically designed for your environment?

One of the often overlooked comparison points of WAN optimization is simplicity.  How simple is the product to deploy?  How much IT staff is required for the initial deployment and ongoing maintenance?  test each vendor by timing how long it takes from un-boxing to optimization.

4.  Product Features and Breadth of Capabilities

You may be surprised that product features is this far down on the list.  The truth is that once you test for speed, scalability, and simplicity, the product features usually take second stage.  For example, if your application is SSL-encrypted, vendors that have developed SSL acceleration features should rise to the top during your testing.  Vendor acceleration features in the areas of web-based apps to Lotus Notes optimization to thin client acceleration vary greatly as do their ability to accelerate these applications. Beware of vendors that claim acceleration of an application only to find out they they don't solve the latency impact on performance.  Once again, make sure your applications are part of your WAN optimization test plans.

There are features very applicable to WAN optimization that are not necessarily about optimization or acceleration specifically.  For example, the ability to provide end-to-end visibility into the network and applications is important for both identifying additional opportunities for optimization along with monitoring the effectiveness of the WAN optimization devices themselves.  Some vendors offer a robust visibility solution while others are well behind in this important aspect of WAN optimization.

Another feature to look for is the ability to run branch office services such as domain controller, print, DNS/DHCP directly from a WAN optimization device.  A number of vendors provide a virtualization layer where you can run these services on their box, providing the ability to consolidate a number of servers and appliances at the branch.  Think branch office box functionality.

5.  Company Viability and ability to Support

Last, but certainly not least is the viability of the vendor and their ability to adequately support their product.  A WAN optimization solution can be a big investment with great value and a tremendous ROI, but your investment could be a bad one if you choose a vendor on the way down, instead of up.  Is the vendor's business growing or shrinking?  Do they have ample resources to focus on your success after the sale?  If you are a global company, do they provide global support?

If you would like to hear from me specifically about Riverbed's response to each of the above five points, please respond and let me know.  I would also love to hear your feedback and if there is maybe something I missed.

The ABCD's of WAN Optimization

What is the first thing you think of when the term "WAN optimization" is discussed?  Believe it or not, the majority of IT professionals continue to associate WAN optimization technology solely to environments where bandwidth challenges exist.  While optimizing bandwidth is indeed one of the key value propositions of WAN optimization, there are a number of additional core value propositions that in many cases present an even higher value than bandwidth savings alone.

What are these areas that WAN optimization impacts?  Instead of going down the confusing path of going over the specific areas in detail, I'll try to make it as simple as ABC or in this case, ABCD.  A for Application Acceleration, B for Bandwidth Optimization, C for Consolidation, and D for Disaster Recovery.

Application Acceleration

Let's face it.  Most business applications have been developed with the local area network in mind.  Applications ranging from Exchange to Lotus Notes to web-based applications like SharePoint, SAP, or Oracle all perform well when clients access servers over a low latency, high bandwidth LAN.  The challenge is that as soon as you extend these applications to the WAN or increase the distance between the client and the server, application performance is poor and in some cases, up to 100 times slower.  Operations that took seconds now take minutes.  The ability to provide LAN-like performance for applications that branch office and mobile workers rely on is arguably the cornerstone value proposition of WAN optimization.   

Bandwidth Optimization

As I mentioned previously, overcoming bandwidth challenges continues to be one of the key reasons to deploy WAN optimization.  Contrary to popular belief, bandwidth is not free and in fact can be very expensive.  WAN optimization essentially eliminates all the data redundancy and the result is that between 65% to 95% of traffic is eliminated from WANs.  The result is that congested links become uncongested, smaller links perform as if they were bigger, and the need to upgrade bandwidth is deferred or eliminated altogether.  Very simple to understand ROI.

Consolidation / Cloud Computing

We have seen the pendulum swing from a centralized IT infrastructure during the 70s and 80's with central mainframes to a massive build out of a distributed IT infrastructure during the 90's where 6 million plus branch offices have been equipped with local servers.  Over the past decade or so there has been a big move back to the centralized, consolidated model where organizations want to simplify their IT and cut costs by consolidating expensive to manage branch office equipment to central data centers.  Relatively recently, we are also seeing an increased interest in moving from this private cloud data center centralized environment to a public cloud environment where infrastructure is hosted by 3rd party vendors like Amazon, Microsoft, etc.  While consolidation obviously makes sense, the challenge is performance.  When you move your file servers, mail servers, and app servers thousands of miles away from your users, performance takes a beating.  WAN optimization becomes vitamin or or the pain killer for consolidation projects.  As a vitamin, WAN optimization is the essential enabler for projects where consolidation has yet to take place.  Replace branch office servers with a WAN optimization device and users in most cases won't notice a difference, even though their server is now removed from their LAN to a data center that is thousands of miles away.  WAN optimization can also be the pain killer for organizations that have already consolidated, but have performance issues.  WAN optimization is essential for the success of any consolidation project.

Disaster Recovery

One of the often misunderstood values of WAN optimization is the impact on disaster recovery and business continuity.  The value is quite simple to understand.  WAN optimization dramatically reduces the time it takes to perform data backup operations either between the branch office and the data center or between primary and backup data centers.   For example, SnapMirror operations are in many cases 30 to 50 times faster.  Operations that take 30 hours to replicate terabytes of data can be reduced to just a couple of hours.  The impact here is that organizations that are having a hard time meeting their RTO (Recovery Time Objective) and RPO (Recovery Point Objective) need WAN optimization.  Shorter backup and recovery times combined with the fact that you can perform backup and replication operations more often, results in a much better RTO and RPO.

There you have it.  Understanding the true value of WAN Optimization is as easy as ABCD.  Thanks to Andy Rogerson at Riverbed for coming up with this clever methodology for remembering how WAN optimization impacts IT initiatives.  I would also like to add that not all WAN optimization products are the same.  Riverbed is widely recognized as the market leader with a best of breed WAN optimization suite that has been deployed by more than 7000 customers to address application acceleration, bandwidth optimization, consolidation, and disaster recovery initiatives.

Faster than a speeding rollout

Well folks,

I thought we had seen it all when Bankwest, formerly part of HBOS Australia, was able to put 170 Steelhead appliances into production across Australia in only 45 days. The professionalism and dedication of Bankwest's IT staff, together with help and support from their VAR Dimension Data & the local Riverbed team helped them to achieve a very large-scale IT infrastructure rollout in a remarkably short period of time.

Of course, the Steelhead appliance's famed simple installation, product stability and ease of use, together with centralised configuration & management, including a fully automatic installation capability from the CMC probably also helped achieve this goal.  ; )

That being said however, another APAC banking customer has just recently blown this record away. A nation-wide bank in Malaysia has just deployed OVER 100 Steelhead Appliances all across the country in ONLY TEN DAYS.

Not bad for a country containing two separate regions, 11 states and about 28 million people.

The R-Team Rescues Replication

“If you have a Replication problem, if no one else can help, maybe you should call the R-Team”

As the Senior Sales Engineer for Australia (a continent the size of North America), I’ve become used to our clever Australia/New Zealand SE team solving tough problems for customers over the past 3.5 years.  However, once in a while, customers make things even more interesting by asking us to “deliver the impossible”.

Read on for more details of how the R-Team allowed an Enterprise customer to deliver EMC SRDF/A replication between States without expensive increases to WAN bandwidth.

In early 2008, the phone rang at the R-Team Australian HQ, with an interesting request from one of our large customers.  This customer, impressed with the WAN Optimization delivered by our Steelhead appliances across its Global WAN, asked if we’d be able to help with a large Disaster Recovery initiative that was facing challenges. 

The customer had just purchased two large EMC DMX Symmetrix storage arrays (one in Sydney, the other in Melbourne) and wanted to implement SRDF/A replication between the Cities for their mission critical systems.  The problem?  EMC’s detailed analysis of their rate of change of ‘track’ data on the arrays meant that they’d need an expensive and dedicated 100Mb/s link between States, while what the customer actually had was a 20Mb/s link which needed to be shared with their usual WAN traffic (Email, file sharing etc.)

Knowing that the smart Engineering team at Riverbed had incorporated the ability to optimize SRDF/A Data Replication data into RiOS™ (the Riverbed Optimization System) and that we were working together with EMC on formal SRDF/A qualification, one of my colleagues (another senior member of the Australian SE team and a Cisco CCIE) sprang into action to solve this customer's immediate challenge.  Through focus by Riverbed, our loyal customer, our storage-savvy Partner and EMC’s Australian SE team, this particular customer’s configuration was tuned and certified under EMC’s custom qualification program.

The joint EMC and Riverbed solution was a roaring success and enabled the customer to “deliver the impossible” – replicating its Enterprise systems across States via SRDF/A without increasing bandwidth - and it has been in Production since mid 2008.

Top 10 Storage Inventions of All Time

Byte and Switch recently wrote about the top 10 storage inventions of all time and while I agree with most of the items on the list, they seem to have left off WAN optimization or Wide-area Data Services (WDS)!

Although data-deduplication is listed as #8, the context is with regards to data at rest and not data in flight.  This list item is obviously aimed at the specific impact that data-deduplication has on data that resides on the storage device.  There is a strong argument to be made that data-deduplication for data in-flight combined with the other performance optimizations that WDS provides has proven to be an important invention that impacts storage directly.  You might be asking how does WDS impact storage?

Customer increases bandwidth by 462 times...holy cow!

A customer in the not-for-profit rehab business recently shared with me how they are using their Riverbed Steelhead appliances to optimize the traffic over their WAN when anti-virus signature updates have to be applied from the central data center to user's branch office and remote worker PCs.

I have to warn you that the following results are unbelievable:

Riverbed customer testimonial - Silicon Image

Peeling back the Onion on a Sales Call

It's interesting to see how "potential customer" interests have changed over the last 5 years.

In 2003, when I was first meeting with customers, talking about this product we were working on, everyone agreed that they had challenges in their network with remote users. The challenges varied — either performance of centralized applications/servers, or backing up their remote servers (ok, and a few who wanted to centralize).  But everyone blamed bandwidth as the culprit for poor performance.  Often they couldn't afford the larger links, but sometimes they had already upgraded and were scratching their heads as to why it didn't help as much as last time.

So, since they viewed it as a bandwidth problem, we'd explain our killer compression (SDR), and they'd spend 90% of the meeting focused on that, then graciously allow us to talk about what we wanted to discuss, which was how transaction prediction (and VWE) would ameliorate the effects of latency and really speed things up. Sometimes light bulbs would nearly visibly go off over people's heads, usually I got a "hm, I'm sure that'll help too, now back to SDR, what happens when..."

Later they'd test the product (as no one believed our speedup claims...remember WDS hadn't even been invented as a term and we were this dinky startup), and be amazed.  The vast amount of their speedup, of course was due to transaction prediction, the majority of the time.

So, how about 2008?  Last week I was meeting with a large financial enterprise, discussing their challenges.  They knew that latency was the root of application performance problems, and we spent most of the time talking about that (still did discuss SDR — as they'd rather not get more OC3s).  But they were puzzled with their test results — things were clearly faster (i.e. stopwatching user actions), and the reports showed dramatic bandwidth reduction on the Steelhead, but the routers reported the WAN links were still full — where were the "savings" coming from.  Anyone see the answer to this mystery?

Well, the data reduction enabled more traffic to flow, and the transaction prediction stopped applications being bottlenecked on the WAN, also enabling more traffic to flow, so...  People got more done — in the same amount of time — thus the WAN was "full again."  It's sort of Parkinson's Law experienced in a different domain (and with a more hopeful spin).

So, how far have we come?  It's mixed, the great news is that people are aware of latency and it's insidious effects.  We still have a ways to go with the second order implications of this though, i.e. that filling a WAN link can actually be a good sign.  And someone needs to come up with a way to measure ROI on knowledge workers — surely them getting more done in a day is valuable to the enterprise. 

So, what do you think...Latency*chattyness is now well understood, or still breaking news?

Can Riverbed save the internet from Doomsday?

AT&T recently warned that the internet will run out of bandwidth in two years.  It sounds crazy, but Jim Cicconi, AT&T's VP of Legislative affairs says that the current systems that constitute the internet will not be able to cope with increasing amounts of user generated content and video.  He went on to say that in three years time, 20 typical households will generate more traffic than the entire internet today!

When you think about it, this doesn't sound so far-fetched. 

The Key Components of WDS

While numerous enterprises have begun deploying WDS solutions, the technology is relatively new.  Many in the IT community are still struggling to understand how WDS technology works.  Compared to say, routers and switches, and other mainstream solutions where technical expertise is readily available, there is a general lack of experts knowledgeable about how WDS solutions work.  Tragically, this has created an environment where seemingly all-knowing charlatans can spout their so-called wisdom to serve their own purposes.

Welcome to the Think Fast blog

From our experiences interacting with the community at the WDS Forum, we know there are lively ongoing conversations about wide-area data services, acceleration, consolidation, and related topics.  We're adding one more source of information here as we initiate Think Fast, our Riverbed corporate blog. Our goal is to be concise, accurate, and helpful -- we want to extend our focus on customer success to this additional vehicle.

We love learning what really matters to you. We also really value our opportunities to explain the ideas and motivations behind our products, and their place in the larger IT universe.  We hope this blog enables more of these great interactions, and we're looking forward to them.
