Sync to Central and edge protection mitigate my risk in our branch offices
Pros and Cons
  • "Sync to Central and edge protection mitigate my risk in our branch offices. All services that need to be local to the user exist on local servers. Users run applications and access data locally while the data is constantly being synced to Central, and protected. If an edge device fails, we can recover quickly."
  • "Setting up disks for use is a multi-step process that could use some refinement. Setting up a core-to-core replication or DR strategy is also cumbersome."

What is our primary use case?

Our company has 12 locations and needs for servers/storage at each one. We have edge devices at all branch office locations, and our SteelCentral is in our Denver, CO location. All servers run on the virtualization layer on these boxes and are provided SteelFusion disks for syncing with Central. The data is synced to our data center and lives on Nimble storage. From there, we replicate to our other Nimble array located in San Francisco. This allows us to provide edge services while ensuring the data is in one location.

How has it helped my organization?

All services that need to be local to the user exist on local servers. Users run applications and access data locally while the data is constantly being synced to Central, and protected. If an edge device fails, we can recover quickly.

What is most valuable?

Sync to Central and edge protection. These mitigate my risk in our branch offices.

What needs improvement?

Setting up disks for use is a multi-step process that could use some refinement. Setting up a core-to-core replication or DR strategy is also cumbersome.

For how long have I used the solution?

Three to five years.

What do I think about the stability of the solution?

No real issues with stability. Every once in a while a controller fails and we have to replace it, but the site recovery manager is a pretty sweet tool that works really well.

What do I think about the scalability of the solution?

No issues with scalability. There are boxes for every size environment. We migrated our SF office from multiple servers to a single SteelFusion box. It was expensive but it works really well.

How are customer service and support?

The level of tech support depends on who you get. There are some techs that just read the script and ask you if you’ve rebooted, but once you get past that - or if you have a very technical issue - the support is great. They really know the product and get you up and running again ASAP.

Which solution did I use previously and why did I switch?

No previous solution. We replaced traditional servers/backup in offices.

How was the initial setup?

The initial setup is both straightforward and complex in certain ways. Doing the controller setup and Virtual Services setup is pretty simple, just follow the steps in the wizard. Once that is complete, however, it does take some planning to right-size disks, apply those to the SteelFusion core, then push those out to the edge for use in the VMs. It is not a complicated process, just a lot of steps.

We also made mistakes with not correctly sizing the volumes and that was a difficult thing to change in the earlier versions of the SteelFusion software.

What's my experience with pricing, setup cost, and licensing?

Price is an issue – this is expensive stuff. My advice is to beat up Riverbed as much as possible on price. These things are expensive and there is room for negotiation.

Which other solutions did I evaluate?

We did not evaluate other options. There wasn’t much out there five years ago when we started looking.

What other advice do I have?

I rate it nine out of 10. It’s great, but not perfect. I have spoken at conferences in the past on behalf of Riverbed. I do believe strongly in the solution.

Understand your environment, ensure you have good storage in your main data centers, evaluate the product in a real-world environment, not just a test environment. Know that if a controller fails, that set of files will be unavailable until the controller comes back up. So, if you need branch office to branch office file sharing, look into other solutions, like Panzura or Nasuni storage.

Even though there is a wide distance between the datacenter and the branch, it maintains the “Read Ahead, Write Behind” philosophy.

The Riverbed SteelFusion (aka Granite) impressed me the moment it was introduced to me 2 years ago. I remembered that genius light bulb moment well, in December 2012 to be exact, and it had left its mark on me. Like I said last week in my previous blog, the SteelFusion technology is unique in the industry so far and has differentiated itself from its WAN optimization competitors.

To further understand the ability of Riverbed SteelFusion, a deeper inspection of the technology is essential. I am fortunate to be given the opportunity to learn more about SteelFusion’s technology and here I am, sharing what I have learned.

What does the technology of SteelFusion do?

Riverbed SteelFusion takes SAN volumes from supported storage vendors in the central datacenter and projects the storage volumes (aka LUNs) to applications and hosts at the remote branches. The technology requires a paired relationship between SteelFusion Core (in the centralized datacenter) and SteelFusion Edge (at the branch). Both SteelFusion Core and Edge are fronted respectively by the Riverbed SteelHead WAN optimization device, to deliver the performance required.

The diagram below gives an overview of how the entire SteelFusion network architecture is like:

It is taken from the SteelFusion Product Guide, which I am using as my main reference. However, I much prefer this diagram here:

Just remember to substitute Granite with SteelFusion. ?

The secret sauce to ensure the “local performance” experience at the branch is BlockStream. BlockStream is RiverBed patented technology that gels and integrates the data from the storage vendor’s iSCSI and Fibre Channel LUNs via SteelFusion Core, and projects a working data set to the SteelFusion Edge at the branch level.

SteelFusion Core is the storage delivery controller. Supported storage vendor platforms include EMC, NetApp, Dell, and IBM. They are also the storage vendors which have been tested with SteelFusion for their respective snapshot integration as well. The solution also can work with any other iSCSI or FC-SAN out there.

SteelFusion “wraps” the respective storage volumes and projects the data working set to SteelFusion Edge. Once the projected working data set is at the SteelFusion Edge, it is provisioned via the iSCSI protocol to various applications and hosts.

The centralized data in the form of LUNs are delivered to the SteelFusion Edge at the branch into BlockStore. BlockStore is an in-memory, persistent caching structure in the SteelFusion Edge device. It serves several key functions, most notably as the authoritative cache for local storage blocks. Frequently Read storage blocks are retrieved directly from the SSDs in the SteelFusion Edge, via its Advanced Tiering Cache technology. High Read IOPS applications benefit greatly from the SSDs performance.

All local applications writes are acknowledged at the BlockStore write cache, eliminating the need to have the writes responded from the data center. The writes changes are deduplicated and compressed, and then asynchronously delivered to the SteelFusion Core to the datacenter storage, riding on the very efficient BlockStream protocol with the help of the SteelHead appliances on both sides.

The “Read Ahead, Write Behind” philosophy is maintained beautifully even though there is a wide distance between the datacenter and the branch. This is absolutely crucial in delivering the performance and the experience to the branches applications.

BlockStream builds and maintains the branch experience. I cannot stress this enough because the deeper the adoption of this technology, the more successful the organization’s converged data strategy will be. And the SteelFusion technology has made it looked simple. It is not an easy task, and as Einstein would say, “Everything should be as simple as possible, but not simpler.

In addition to that, BlockStore performs intelligent predictive block pre-fetching. By analyzing the patterns and the frequency of storage blocks requested, it identifies and retrieves these blocks in advance to the Edge device. This is further enhanced with the deduplication technology and optimization by the SteelHeads, reducing the amount of blocks transferred and increasing the performance and experience. With this technology combination, branch applications can boot off the WAN. Riverbed recommends their Turbo Boot software to be installed on Windows machine to deliver only the files required for WAN booting.

Another initiative greatly boosted by Riverbed SteelFusion is Business Continuity and Disaster Recovery. The question on everybody’s mind is often related to the failure of the WAN. The disruption of network communication between the datacenter and the branches would also stop the branch applications too, right? Well, NO!

Because of the various techniques and advanced configurations in the SteelFusion technology, branch applications continue perform as usual. Writes are continually acknowledged locally and reads are fast from the cached blocks in the SSDs of SteelFusion Edge. The “dirty blocks”, the blocks that have not synced with the storage LUNs at the datacenters are shored in the allocated transient memory segment of the Edge device, awaiting WAN continuity. Once the network service is resumed, all these “dirty blocks” are flushed back to the datacenter, closing the entire data cycle.

There are so much more SteelFusion advanced features to share and this entry simply cannot fit all of them. I urge you to go search the web for SteelFusion, and of course, they are always available at Riverbed’s own website.

It is important that data architects take the prerogative to delve deeper when considering a branch convergence data strategy. The data strategy must never be a hodgepodge solution, because the storage infrastructure is still pretty much a dark art domain. Any attempt to disturb how data is delivered from an enterprise storage architecture to the end applications could result in data corruption and affect the data integrity.

That is why Riverbed SteelFusion has delivered a masterclass technology that not only abstracted and virtualized the storage vendors’ unique logical storage structures, it has made it logically closer and seamless to the branch applications from a performance and experience perspective. Riverbed positions this as the solution that separates both compute and storage platform while enabling local performance and I/O response, regardless of location or distance.

We all know end users of applications are a difficult bunch to please, and any lag in applications delivered via a remote distance will ruin the user experience. As I have said in my previous blog, the technology adoption is inverse to the user experience. Riverbed SteelFusion breaks down the barriers of branch technology adoption and can only bring greater data convergence success in any organization’s inclusive data strategy.

This technology, the Riverbed SteelFusion, to me, is one true data convergence architecture.
