Eliminating Noisy Neighbors in the Public Cloud
Grazed from NetworkComputing. Author: David Hill.
One problem with multitenant public cloud environments is the "noisy neighbor" phenomenon, when one or more customers monopolize available resources and thus significantly degrade the performance of other customers’ systems. One way to address this problem is via storage-based quality of service that provides defined service levels to all tenants. An infrastructure-as-a-service provider, CloudSigma, is using all-SSD arrays from SolidFire to create an architecture to eliminate noisy neighbors.
CloudSigma has decided to replace all of its Tier 1 primary storage hard disk arrays with SolidFire all-SSD arrays. In addition to this significant move, the company also offers solid-state drive storage at the same price as hard disk for the same capacity. How can CloudSigma do this when flash memory is more expensive on a per-unit basis than hard disk?…
