SolidFire launches SSD
cloud appliances
Editor:- June 21, 2011 - SolidFire has
announced details of its first product - an
iSCSI SSD appliance
designed for cloud storage
applications which the company says can scale to 1 petabyte capacity (which
takes 100 nodes with current models).
Performance within a SolidFire
system is virtualized separately from capacity, allowing cloud service providers
to prescribe and guarantee performance to every volume within the system.
Editor's
comments:- the company's
SolidFire
elements include features such as:- self healing data protection, always on
availability,
reservation-less thin provisioning , inline real time compression,
cloning and snapshots,
and dedupe, as
well as adjustable managed
IOPS and
throughput performance windows.
These are the essential
characteristics of what I called "bulk storage SSDs" in my article
roadmap to the
Petabyte SSD - although in that article what I had in mind is that by 2016
that a PB archive SSD library should fit into a single 2U rackmount.
If
that seems far fetched - remember that a lot of things can change in the SSD
market in 5 years.
5 years ago -
in 2006 - the enterprise server flash SSD market didn't exist. 2006 was
the 1st year of the
notebook SSD
market and there were only 36 makers of SSDs - compared to 300 today.
SanDisk samples 800GB 3.5" SAS SSDs
Editor:-
June 20, 2011 - SanDisk
has expanded its
Lightning
range (2.5"
and 3.5"
SAS
skinny flash
SSDs) which now offer upto 800GB MLC capacity are being delivered for OEM
qualification, and will be available via authorized channel partners in Q3,
2011.
The new Lightning SSDs (recently acquired from
Pliant) feature
Write Through Logging (WTL) technology which delivers high performance at low
queue depths to avoid volatility that would otherwise require battery back-up or
supercapacitors for protection. WTL operation is completely transparent to the
host and maintains a predictable performance profile across different workloads.
This write cache-less design
eliminating
data loss on power interruptions, delivering consistent performance across a
wide range of workloads
virtual server acceleration mistakes
Editor:- June
20. 2011 -
5 Mistakes to
Avoid when trying to solve I/O Bottlenecks in Virtualized Servers is a new
article by IO Turbine
published on StorageSearch.com.
Needless
to say most of the discussion in here revolves around the best use of SSDs.
Among other things - IO Turbine says "While many enterprise-class storage
providers offer automatic tiering with data migration to and from the SSD
storage, these solutions typically take place well after the need for the I/O
acceleration has passed." ...read the
