| Feature |
Benefits |
|
Host interface intermix |
- Support for intermixing SAS and Fibre
Channel or SAS and iSCSI interfaces allows for cost-effective SAN tiering
and consolidation
|
|
Balanced performance |
- Equally adept at IOPS and MBps, the
DS3500 is able to support applications with wide-ranging performance
requirements
- Well suited for consolidation and
virtualization environments that have diverse workloads and application
requirements
- Designed to concurrently support
transactional applications and throughput-intensive applications
|
|

System x®, IBM BladeCenter® and IBM Power Systems™ servers |
- With its simple, efficient and flexible
approach to storage, the DS3500 is a cost-effective, fully integrated
complement to System x, BladeCenter and Power Systems servers.
|
|
Support for SED drives |
- Comprehensive protection for
data-at-rest helps ensure data is secured throughout the drive’s life
cycle without sacrificing performance or ease of use
|
|
Scalability up to 192 drives |
- “Start small, grow big” provides the
flexibility to grow with their data needs
- Not locked into high-quantity drive
purchase at initial purchase
|
|
Support for drive intermix |
- Ability to intermix high-performance
SAS, near-line SAS and SED SAS drives enables tiered storage
- Cost-effectively support an
organization’s complete range of data capacity requirements—from
near-line to highly utilized applications—with support for mixed drive
types within a single storage system
- Enclosure-based intermixing maximizes
efficiency
