EMC on Monday launched the "Project Lightning," now
called the VFCache product line, an initiative to sell
PCIe-based NAND flash cards for servers as a caching
element to increase I/O performance by up to 4,000
times.
The EMC VFCache is a new server Flash caching
solution. Together, VFCache and EMC Flash-enabled
storage systems improve application performance by
leveraging intelligent software and PCIe Flash
technology - EMC's testing resulted in up-to 3X
increased throughput while reducing latency by 60%.
Now databases (CRP, ERM), OLTP, email, Web, and
reporting - any read-intensive workloads with
cacheable working sets - can benefit from the
performance benefits of PCIe Flash.
VFCache combined with VMAX , VMAXe , VNX and VNXe
storage delivers performance with the protection (high
availability, data integrity, reliability, and
disaster recovery) for which EMC storage.
VFCache cards install into a server's standard PCIe
slot, and come with a filter driver that runs in the
host server. As the host issues an I/O operation, the
VFCache driver intercepts it, checks the table in its
memory as to what data is in the cache, and if the
data is on the flash memory it serves that I/O read
request from the server; If the data is not in cache
memory, the driver sends a read or write request
through the storage area network to an EMC storage
array.
Placing Flash technology in the server on a PCIe card
can accelerate performance up 4000X faster data access
than 15K HDD, according to the company.
Coming in the next year, EMC will add deduplication
technology to VFCache, enabling its customers to
achieve even more efficiency from Flash technology.
Additional Flash capacity and form factors will also
be supported. VFCache will also more deeply integrate
with EMC storage management technologies, and
additional integration with FAST architecture.
EMC also plans an early customer access program for
"Project Thunder" in the second quarter of 2012.
Optimized for high-frequency,
low-latency read/write workloads, it will build upon the
PCIe technology delivered in VFCache to leverage the
power of Flash through a dedicated server networked
Flash-based appliance. The appliances will be
connected to server farms through the InfiniBand
network protocol. They will hold five, 10 or
15 PCIe cards, according to EMC. |
