ArxCis NVDIMM Key Features I.
•Fastest storage tier, 11GB/S, DDR3 DIMM speed & bandwidth
more than 300% faster than PCI-E (3.2GB/S).
•1.4 million IOPS Read & Write, 3 times faster than PCI-E cards.
(430K Write IOPS)
•DRAM chips never wear out, no limit on number of writes.
•DIMM interface “talks” to CPU more directly.
•1000x better latency performance than PCI-E, 10 nanoseconds
vs 10 microseconds.
•Complete solution with supercap, monitors supercap health.

ArxCis NVDIMM Key Features II.
•Use as RAMDISK, and data will be saved in event of power
failure. (PRAMDISK)
•Faster recover from power failure, back to system environment
before power failure.
•Support Instant On, apps layer data kept in flash, fastest boot.
•Configure as block device for caching, performance +
endurance.
•Memcache application pushing up demand for NVDIMM.
•Support both ADR & NMI power failure data saving functions.
•Intel’s chosen partner for NVDIMM enablement for Grantely
platform.

ArxCis NVDIMM, Perfect Match For SSD based
Enterprise & DCN Systems.
-Removing need to write on SSDs, extend life of SSD based
servers.
-No need over-provisioning, releasing extra storage space from
SSDs.
-No operation cycles wasted on wear leveling.
-No longer a “write cliff”, nor need to closely monitor drive usage.
-Rapid increase in ROI for enterprise or data center applications.
