The enterprise storage market is in a transitional state with newer all-flash arrays and hyper-converged infrastructure disrupting legacy storage architectures. If for whatever reason your company is not in a position to consume these newer technologies, what choices exist to extend the investment in your legacy platform(s)?
Typically, you will be looking to achieve performance gains and/or reclaim storage capacity for redeployment. A starting point is to review/create IT information retention policies and remove stale or duplicate data to ensure policy compliance, this includes array level snapshots where multiple copies can exist. Also consider retiring unused devices and applications and relocate non-critical data to an alternate lower service level platform. Where possible limit test / development / QA environment sprawl.
From a technical perspective evaluate space saving features such as data deduplication and compression for appropriate datasets. Thick LUN utilisation should be reviewed and where feasible convert these into Thin LUNs to reclaim capacity. For non-CPU bound storage platforms, the addition of solid state technology (cache layer and/or sub-LUN auto-tiering) can have a positive impact on the overall system performance and reduce environmental costs. The deployment of server-side PCI cache may remove I/O workload from the storage array. The use of server virtualisation can reduce the server count attached to the array and free network switch ports.
