In the Tintri 2015 State of Storage report, survey results indicate that for data center professionals ensuring storage system performance (50%) and managing data growth (40%) are top concerns. As the amount of stored data grows exponentially, management of this information remains an increasingly difficult challenge for many organizations to tackle.
Undoubtedly, flash storage is one of the most expensive commodities we can buy for our data centers. As a result, most companies are forced into a hybrid model where they run a combination of disk-based and flash storage. Notably, as the enterprise adoption of flash increases, the continuous prioritization of workloads on flash vs. disk is crucial to both performance and efficiency. In other words, workloads that demand a lot of IOPS should be able to access flash storage, while more idle workloads can do with disk. The challenge is ensuring the specific storage demands of these workloads are met continuously and in real time.
Storage latency, and how to improve upon it, is just about the hottest topic out there as it relates to virtualization. Walking around the floor at VMworld, what stood out to me the most was the number of vendors focused on storage performance. Hardware vendors, software vendors, combinations of both, all focused on improving, in some incremental way, the manner in which business data is delivered from the storage infrastructure.
