mSF is specificcally designed tto minimize CP

DATA
the server by offfloading these flash managem
ment operation
ns from the ho
ost CPU to the
PCIe card. XtremSF also delivers continuity of operations in the event that there are
failures within the flash media itself. Leveraging redundant array of independent NAND
(RAIN) technology, flash components on the card can be isolated as separate slices and
spread across RAIN groups, allowing for multiple failures to occur without disrupting an
application’s access to the data. This enables complete, transparent data recovery if a
single storage element fails, as the device automatically detects it and transparently
rebuilds the data without affecting any existing user data or drive performance.
Organizations that want accelerated performance with protection can couple XtremSF
with XtremSW Cache software. While accelerating reads, XtremSW Cache
simultaneously delivers enterprise-class protection of mission-critical application data.
The software caches an application’s most frequently accessed data on the PCIe flash
card in the server for maximum performance, and leverages a write-through algorithm
to ensure that newly written data persists to the networked storage array for persistent
high availability, integrity, reliability, and disaster recovery.
With XtremSF, today’s IT organizations can realize unprecedented gains in application
performance, along with unconditional performance over the entire lifecycle of the
device. These benefits are revolutionizing the way leading IT organizations are thinking
about their future server and storage architectures in order to maximize application
performance.
