LICENSE TO KILL
Mainstream companies are starting to reap benefits from
harnessing unused computing power. By lashing together sometimes
hundreds of servers to create a powerful grid, businesses are
using their technology better. But software licensing,
organizational and cultural issues, and data management can be
barriers to grid adoption. Find out how to overcome these
barriers - click here:

Today's focus:
Multivendor provisioning grows easier with new storage
virtualization wares
By Joanne Cummings
Storage virtualization isn't a new concept, but it's getting a
lot of attention lately as the top storage vendors launch
next-generation virtualization wares. The vendors vary on their
approaches - some put virtualization in the network, while
others put it at the edge or in the array - but they all attack
the same basic problem: simplifying storage management.
In traditional storage setups, the intelligence necessary to
perform key storage functions such as snapshot copying, data
replication and disk mirroring are handled primarily at the host
or server level. Implementing virtualization, in which servers
view all enterprise storage devices as one large pool of
storage, means adding the software, device drivers and so on to
each individual server - a situation that is notoriously tough
to manage.
The first attempt to move the intelligence necessary for storage
virtualization into the network came in 2000-2001 with
appliances such as DataCore's SANsymphony and FalconStor's
IPstor. These appliances let users pool storage while
eliminating the need for drivers and licenses for each server.
But this approach never really caught on, primarily because the
main Tier 1 storage vendors didn't play along. "We looked at
FalconStor's IPstor appliance when we put in our SAN a while
back," says Bo Christiansen, IT consultant at SDC Udvikling, a
Copenhagen, Denmark, financial firm. "It raised the possibility
to integrate the different storage technologies under one GUI,
which we liked. But there were some problems with how it worked
and vendor lock-in. We decided to wait to see if we could get
the virtualization without being locked in to a small vendor."
IBM became the first large vendor to embrace virtualization
fully with its SAN Volume Controller (SVC), introduced in July
2003 as a network appliance or as a blade within Cisco's MDS
director-level SAN switch. IBM has made considerable headway
with the SVC since last August, when it added the ability to
manage arrays from Hitachi Data Systems, HP and EMC; the company
announced its 1,000th customer this March.
Hitachi has since rolled out its TagmaStore array-based
virtualization, and Sun its StorEdge 6290 controller/array
system. And EMC hit the market in May with its Invista
virtualization software, which runs on Cisco, Brocade and McData
director-level switches.
This is all good news for users, who are struggling with
explosive growth in storage coupled with the need to better
manage stored data because of compliance pressures.
