Release Note

Cisco Unified ICM/Contact Center Enterprise & Hosted Editions, Release 7.5,

Hardware and System Software Specification

3. The SAN host interface (for example, Fibre Channel) must meet or exceed the performance specifications

of supported (direct attached) SCSI/SAS interfaces (see

Storage Hardware, Required Controllers, above).

4. Each individual drive in the SAN array must meet or exceed the performance specifications of supported

(direct attached) disk drives (see

Storage Hardware, Disk Speed, above). (Note: SATA drives are not

supported with SAN.)

5. The SAN disk array must be configured as RAID 10, for added performance and fault tolerance.

SAN solutions are typically deployed in a shared environment where multiple applications are contending for storage

access. Because of the real-time nature of the Unified ICM/Contact Center application, such an environment cannot

be supported; the conditions listed above are necessary to ensure that the deployment performs within published

capacity limits. If the SAN storage deployment is identified as affecting the functions of the contact center solution,

the customer will be required to deploy a direct attached storage solution instead. Moreover, if in the process of

troubleshooting, the SAN itself is identified as the problem, the customer must contact the system integrator or the

SAN vendor for resolution.

Unqualified backup options:

• Backup device/software option decisions (and procedures) are left to the end customer; no backup products are

explicitly qualified by Cisco.

Caution

For performance reasons, backups must be performed outside of business hours or during periods of lowest activity.

Cisco does not provide recommendations for specific backup devices or products, but internal and other direct-

attached devices might have restrictions on which platforms they are compatible with. Consult your backup product

vendor to determine options for internal or external backup storage.
