by making storage simple to deploy while keeping data protected from risk and highly
available.
Experience has shown that enterprises that deploy the XIV system have achieved:
►
up to 70% savings in tier-1 capacity costs
►
up to 80% savings in power, space and cooling costs
►
up to 80% savings in ongoing system management costs
The simplicity of buying and configuring an XIV system further reduces its overall TCO,
by eliminating hidden costs and reducing the overhead typically associated with bringing
new technology and systems into a data center. The XIV system's use of density-to-cost-
efficient VHDSR drives slashes capacity costs by requiring fewer disks and associated
operating costs: each disk requires less power, cooling, and space, as well as less
supporting infrastructure and add-on software.
The calculations provided here assume that MDFR drives are replaced by the equivalent
amount of VHDSR storage. But this assumption actually grossly overstates the
requirements. If a storage project has a significant non-utilization rate – and this is not at
all unusual – then eliminating the unused storage can slash up to 70% of the cost right off
the top.
XIV's self-balancing, single-tier architecture, with advanced monitoring and failure alerts,
requires less training, management, and planning than the typical enterprise storage
system – and much less unplanned downtime.
In a nutshell, the IBM XIV Storage System takes a breakthrough approach on multiple
levels to deliver a total cost of ownership that is dramatically lower than that typically
associated with high-end storage solutions offering comparable functionality and services.
