d. Memory
Installed memory must be an exact match for what Cisco has certified to be supported; i.e., exactly the same vendor,
make, model, specs, and third-party part numbers. For guidelines on memory upgrades and replacements, see:
http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_tech_note09186a00801fa026.shtml. Different
memory configurations (module quantity and size) must not be installed because they are not certified. The Cisco
Unified Communications Manager software and kernel are optimized for specific memory configurations, so higher
amounts of RAM will not help. In general memory changes are supported only for spares (vs. relying on Cisco
SMARTnet coverage and RMA), or to enable upgrading to a new Cisco Unified Communications Manager release.
Cisco does not support migrating from one server class to another via CPU, RAM, or disk changes.
Table 38 below only contains SKUs for latest and greatest server generations. If you need memory for an older
server generation, please see the ordering guides for Cisco Unified Communications 7.1 and 8.0.
Cisco no longer stocks HP components. . Order these direct from the HP using exact part numbers at

e. Hard Drives
Installed hard drives must be an exact match for what Cisco has certified to be supported; i.e., exactly the same
vendor, make, model, specs, and third-party part numbers. Different hard-drive sizes, vendors, or models must not be
installed because they can introduce untested/incompatible RAID firmware and drivers that will cause installation
failure or system instability. In general disk changes are supported only for spares (vs. relying on Cisco SMARTnet
coverage and RMA), or to enable upgrading to a new Cisco Unified Communications Manager release. Cisco does
not support migrating from one server class to another via CPU, RAM, or disk changes.
Match the SKU in Table 39 with the model generation of the server you use. This section only contains SKUs for
latest and greatest server generations. If you need disk drives for an older server generation, please see the ordering
guides for Cisco Unified Communications 7.1 and 8.0.
