Nimble and Silver Peak: Better Together

You’ve heard from us how much Silver Peak improves replication performance, now hear it from the field. CIO Solutions, a Nimble storage partner based in California, recently published their performance testing with Nimble and Silver Peak:

My prior experience with WAN optimization had been with Riverbed and the Juniper WX product (use to be Peribit) that no longer exists. There were three things about the Silver Peak story that resonated with me compared to my prior experiences with Riverbed and Juniper WX.

  • Software not hardware…read they specialize in virtualization(software) solutions and provide an OVF for install. This is their recommended deployment model rather than a supplement to their hardware.
  • Simple…they optimize at layer 3 and for the most part are application unaware. This means much simpler configuration and a “set it and forget it” mindset.
  • Focused, they only do WAN optimization. Riverbed’s current story, Post IPO, seems a little “public market pressure to grow combined meets marketing spin” i.e. all the acquisitions/new products SOUND like they are related but then once you really think about the new riverbed technologies and their interrelationship it feels like riverbed might be trying to fit a square peg in a round hole….

Nimble Storage, for those of you who may not know, is a flash-optimized hybrid storage solution that includes highly-efficient, data replication software for off-site data protection challenges, such as with disaster recovery and backup.  Nimble replication is designed for the wide area network (WAN), only moving changed data to the remote site and only then after compressing it.   Inefficiencies in the WAN though may prevent organizations from realizing the full value of their Nimble implementations.

CIO Solutions examined Nimble-Silver Peak performance across a 100 Mbps connection with 10-15 ms of latency. With Silver Peak deployed, they reduced Nimble-to-Nimble replication traffic by 60 percent and saw throughput improve by a third going from 60 Mbps to 80 Mbps with bursts of up to 300 Mbps.

“In an ideal world replication would be no more than one day behind even though we take snapshots every four hours. With Silver Peak I think 90 percent of the time snapshots will finish replicating in less than two hours. Without Silver Peak we wouldn’t hit that objective, “ Eric Egolf, president of CIO Solutions, wrote in an e-mail.  David Ashamalla, the CTO of CIO Solutions, was even more specific “We went from an average of 196 KB/Min transfer times, to 630 KB/Min, a 31% increase by my calculations, reducing our replication times from about 90 minutes to 30 minutes.”
