Eliminating Noisy Neighbors in the Public Cloud

An IaaS provider is using all-SSD arrays and storage QoS to ensure that some tenants can’t disrupt performance of others by overconsuming resources.

Mesabi Musings

The IT industry does not officially declare "The Year of..." awards, but if it did for storage, 2013 might be called "The Year of All-Flash Arrays." IBM in its recently announced flash initiative stood as a "Good Housekeeping Seal of Approval" for all-flash arrays in data centers based on a purely economic analysis.

CloudSigma and SolidFire have extended that point to public cloud infrastructures. In a multitenant cloud, economics is a critically important consideration, of course, but so is being able to provide a guaranteed QoS. Without predictable performance (and that's not just for performance-sensitive data, but all data on a day-to-day basis), customers cannot commit to a public cloud.

SolidFire eliminates the noisy-neighbor QoS problem, and CloudSigma attests to the technical and economical value of this approach with its full commitment to all-SSD SolidFire arrays for primary storage. To achieve this, SolidFire has created a sophisticated architecture that provides differentiation in the same sense that an enterprise-class disk array is much more than just a bunch of disks. From an economic performance and QoS manageability perspective, all-flash arrays now command the high ground for Tier 1 primary storage arrays.

We all knew that flash's time was coming; what should be apparent to all is that time is now.

Neither CloudSigma nor SolidFire is a client of David Hill and the Mesabi Group.
