Top 5 Questions to Ask Your Flash Vendor

Posted by VIOLIN SYSTEMS on Oct 7, 2013 9:47:44 PM

NAND flash brings with it a new set of terminology; a new set of pros and most certainly a new set of cons.  New flash-based storage vendors are popping up by the dozens.  So, what is an IT person to do with all this new technology?  Simple. Ask questions and when in doubt, test the solution first.

Storage purchases are expected to live in production for at least 3 to 5 years.  Knowing which companies are likely to still be around, what makes their technology different and what makes flash storage the killer new toy or the aggravating purchase you soon regret is based on your understanding of this new technology and how each vendor utilizes it. Read on for the Top 5 questions to ask a flash vendor.

Multi-tenant and Multi-instance Systems on All-flash Storage Arrays

Posted by VIOLIN SYSTEMS on May 9, 2013 5:46:19 PM

Modern hosting and service providers often face the challenge of managing the cost efficiencies of their platform.  A common solution is to deploy a multi-tenant or multi-instance architecture in which many customers share the same hardware.  The reuse of hardware over many clients drives down costs and also reduces the required ongoing administration.

Multi-tenant deployments host many clients in the same instance of software while segregating the client data through configuration.  Multi-instance designs are similar but run one instance of software per client.  To the storage tier, both approaches require many sub-ecosystems to run simultaneously in a shared space and will cause similar access challenges:

  • Unpredictability of usage
  • Height of individual usage spikes
  • Scale versus storage performance (more clients translates into a more random and parallel workload)

The Cost of Compromise: Coping with Spinning Disk

Posted by VIOLIN SYSTEMS on Mar 6, 2013 2:11:41 PM

While servers with advanced multi-core processors and networks with low-latency multi-gigabit per second interconnects have kept up, storage has not. Just how much effort and resource is required to band-aid the performance gaps of legacy storage systems? Many of the tactics listed below are used without consideration for the overhead as well as opportunity cost that they incur, simply because “it has always been that way”:
