Figure 3: Overall TCO: Traditional Tier-1 storage vs. XIV storage
Acquisition Costs
The IBM XIV Storage System is designed to be cost-efficient in all aspects, while
delivering outstanding and consistent performance. The XIV system’s:
►
Single-tier architecture
supports all kinds of storage in one environment and
makes scaling easy
►
Use of
off-the-shelf components
makes customized hardware unnecessary and
makes it possible to integrate newer, state-of-the-art hardware as soon as it
becomes available and without delay
►
Innovative use of
highly economical disk drives
[Very High Density Slower
Rotation (VHDSR) drives]
offers excellent capacity-for-cost value while meeting
enterprise performance standards
►
Built-in
thin-provisioning
allows the acquisition and installation of additional
capacity to be delayed until needed, making it possible to defer capital purchases
and take full advantage of future hardware and price-point improvements not
currently available
