In another demonstration of genuine leadership and street fighting spirit EMC announced today the availability of VFCache, otherwise known as Project Lightning. Simply put, VFCache is a 300GB SLC-flash on a PCIe card, designed to go into a server which is running an IO starved application, perhaps even after using the fastest HDDs and even array-based SSDs. Such applications are more prevalent than one might think. In fact, more and more applications have become IO-starved over the past decade as CPUs and networks have become faster and storage has improved marginally, if at all. The product is also GA at the same time.
Nexsan Corp. today introduced its first multiprotocol storage platform, the Nexsan NST Series Unified Storage System, which contains a flash cache using single-level cell (SLC) solid-state drives (SSDs) and DRAM to accelerate performance.
Servers are growing more and more powerful, but decades-old storage controller technology has not kept pace. This puts storage at an extreme disadvantage just as companies are growing huge infrastructures of virtual and physical systems, applications of all types and very large volumes of primary data.
Mainstreaming High IO Performance with Flash Cache
Advances in solid-state drives have helped by introducing higher performance/lower latency into the computing stack, and customers do not necessarily have to sacrifice simplicity or budgets for performance improvements. However, these SSD products – which may be at the server, network or storage layers -- can be very expensive and complex to deploy and manage even at the enterprise level, let alone the mid-market. Customers want and need the performance boost from SSD products but they are asking if the improvement is worth the expense, management complexity, and confusion around different SSD offerings. The answer is: it depends.
Violin Memory acquired GridIron Systems today, adding GridIron's flash cache SAN acceleration platform to its family of all-flash storage arrays.
Storage professionals building out their infrastructures have more new storage technologies to choose from than ever before, but the choices are becoming more complex.
