Virtualizing The Data Center
Most administrators familiar with virtualization usually associate the concept
with Server or Desktop Virtualization via products from companies like
the storage is a complementary, if not essential, part of the equation.
Storage Area Networks and Virtual Storage
Storage Virtualization is the concept of completely abstracting the disk space used
by your server data from the physical disks or "spindles". In a sense, any volume
that is based on a RAID group or external or shared storage array can be thought of
as a logical or virtual quantity, but Storage Virtualization goes well beyond simple
consolidation or abstraction of disks in a common storage array or the so-called "SAN".
Storage Virtualization allows you to aggregate disks and LUNs from disparate systems
into common storage pools. Different tiers of storage from multiple vendors can be
managed under one pane of glass. Imagine being able to take a snapshot (or BCV)
of a Tier 1 storage array volume onto a lower cost SATA iSCSI array. Imagine being able
to provide a unique remote replication service for any and all of the volumes in
a heterogeneous SAN, replicating to lower cost SATA storage at a DR site. The
possibilities are virtually endless.
Las Solanas Consulting recommends Storage Virtualization
