SANDirect's Perspective
With the release of the VFCache, EMC has brought to the market an IO accelerator product that combines SSD technology with intelligent cache management software. What’s important about this is that EMC is taking the uniquely unconventional approach of showing the mainstream marketplace how SSD can be used to boost the productivity and effectiveness of existing storage systems, instead of suggesting full-on, costly replacement.
In this way, the EMC VFCache accomplishes two critical goals that are at the forefront of concerns over the need to increase productivity while scaling back expenditures and protecting capital investments.
It’s designed to “play well with others.” What this means is that businesses seeking to boost performance and decrease latency don’t have to replace their existing storage arrays and start all over again from scratch. The VFCache was specifically designed by EMC to act as a complement to existing storage systems while improving performance and significantly decreasing latency times.
The VFCache is “human resources-friendly.” One of the greatest concerns that lies at the heart of the need to increase systems performance is the human factor. There’s no denying that with every systems upgrade, employees and other IT professionals have to undergo extensive re-training to learn how to operate systems. In many cases, internal tasks that have been handled the same way for years have to be adjusted in order to align with the nuances of the replacement equipment. This inevitable loss of productivity time is daunting, and has caused many businesses to rethink their need for faster systems when balanced against the potential loss of thousands of man hours.

EMC VFCache: A server Flash caching solution anchored in storage array protection that reduces latency and increases throughput to dramatically improve application performance. Intelligent caching software with PCIe Flash technology extends storage tiering to the server.
Supercharged Application Performance
Supercharge the performance of your read-intensive, high-throughput, minimal-response-time applications by an order of magnitude, and cut latency in half.
EMC VFCache puts data closer to the application, caching the most frequently used data on the server-based PCIe card to dramatically improve performance of read-intensive applications.
VFCache sits in the server on the PCIe bus, so data no longer needs to travel through the network to the storage array. Response time decreases and performance increases by an order of magnitude for applications that require the most I/O.
Automated Intelligence
Extend EMC FAST array-based technology into the server with a single, intelligent I/O path from the application to the data store. Automated intelligence puts the hottest data on the server for optimal application efficiency.
EMC VFCache extends EMC FAST into the server. VFCache automatically adapts to changing workloads by determining which data is most frequently referenced and placing it on the server Flash cache.
VFCache joins FAST to create the most efficient and intelligent I/O path from the application to the data store, creating a true end-to-end tiering solution that optimizes application capacity and performance from the server to the storage.
Total Protection
Get performance with protection—write-through caching means your writes persist to the back-end storage array to ensure high availability, end-to-end data Integrity, data reliability, and disaster recovery.
Other vendors promise only performance with PCIe Flash cards, but EMC VFCache provides performance along with full protection anchored in the storage Array.
Data is protected by the advanced technologies of EMC networked storage for high availability, data integrity, reliability, and disaster recovery.
