OCZ ships 16TB CloudServ auto caching PCIe
SSD
Editor:- February 14, 2012 - OCZ today
announced
imminent shipments of new high capacity
PCIe SSDs optimized
for cloud apps.
The
Z-Drive
R4 CloudServ (which uses 16x
SandForce 2581 SSD
processors) has up to 16TB of storage capacity on a single full height
card and is supported by auto-caching functionality (based on the acquisition
of SANRAD's
VXL) and OCZ's
VCA 2.0
which together enable host migrations without loss of performance or
interruption of service.
Tegile enters the SSD ASAP market
Editor:- February
14, 2012 - Tegile
announced general availability of its
Zebi hybrid
storage arrays - which are rackmount
SSD ASAPs with
internal hard drives and integrated
dedupe,
compression and snapshot.
Virident and NEC publish new Oracle IOPS benchmark
Editor:-
February 14, 2012 - Virident Systems
recently published some
benchmark
results related to the Oracle application accelerator market.
The
system was a single
Intel
Xeon family based (8x 10-core CPU)
NEC
Express5800/A1080a "GX" server - which had 8x 1.4TB
FlashMAX PCIe SSDs
installed - (11TB total) . The integrated solution delivered 1.2 million
random IOPS
and a bandwidth of 9.4 GB/s in real-world Oracle 8k block-size workloads.
Brian Garrett,
VP at ESG Lab - the
company which did the testing for NEC and Virident said - "Our evaluations
of (the products in this system) have revealed that they can eliminate the
performance issues common to real-world workloads and deliver extremely high
levels of sustained and predictable performance for mixed-application workloads.
Virident
has addressed the challenges associated with many first-generation PCIe
flash devices with the multi-dimensional performance capabilities of its
FlashMAX SCM. Most notably, the Virident solution delivers extremely high levels
of performance for reads, writes, and a mix of reads and writes."
Editor's comments:- the
PCIe SSD market has
become the incubator and market proving ground for nearly all the major new
advances in high performance SSD architecture and associated memory management.
And from time to time all the leading vendors publish new benchmarks to
demonstrate just what you can achieve with their products. Although I've
warned before
about placing too much reliance on any single set of benchmark results - it's
interesting to see who is doing how many IOPS with whom and in what context.
NEVEX CacheWorks supports RamSan flash
Editor:-
February 8, 2012 - NEVEX
today
announced
that its CacheWorks
for Windows Server has been tested and optimized for performance with the
new generation of flash SSDs from Texas Memory Systems
- in particular the RamSan-70
(a PCIe SSD) and the
RamSan-810 (a 1U
rackmount SSD).
Dan Scheel,
President of TMS said - "By combining our high-bandwidth, low-latency
enterprise data storage systems with NEVEX's application optimisation cache
software, we provide I/O acceleration for virtualised applications that blows
the others out of the water."
Editor's comments:- In
2010 I
wrote about the sometimes
confusing brand
stretch of "RamSan" - as even back then 70% of the SSDs that TMS
sold were flash rather RAM - and PCIe was a sizable chunk of the product line
mix too.
This software support from NEVEX fills a key functional gap
(SSD ASAP) in the TMS
route to market. Unlike some other PCIe SSD companies (Fusion-io,
OCZ,
STEC and
Micron) which have
acquired SSD software companies in the past year - TMS is still
focusing its design
efforts on hardware and controller chips - while also grooming itself to
look as good as possible for a suitable acquirer. | |

| In literature the novel and
the short story each have their own place. But they work in different ways.
Often one will satisfy your needs as well as the other. But a collection of
short stories isn't the same as a novel - even if the page length is exactly
the same. In the SSD world - the book is the array. And the SSD architecture
tells you if the story on any randomly chosen page has a deep and meaningful
connection to the story everywhere else. |
