1.2.1 HP StorageWorks Scalable File Share Rack Configurations

HP SFS An typical system can consist of a base rack which contains:
• ProLiant DL380 MDS and administration servers, which also function as Object Storage
Servers
• HP SFS20 Enclosures
• A management network HP ProCurve Switch 2626
• KVM switch
• TFT console display
An HP SFS expandable configuration consists of a base rack which contains the MDS and
administrative server, pairs of Object Storage Servers, and the other items listed above. The MDS
server, administration server, and each pair of Object Storage Servers have associated HP SFS20
Enclosures.
An expandable configuration can also have expansion racks which contain pairs of Object Storage
Servers and HP SFS20 Enclosures. The number of expansion racks in the maximum configuration
(32 Object Storage Servers) depends on both the number of HP SFS20 Enclosures for each Object
Storage Server and the type of server used.
An HP SFS system with 10 or fewer Object Storage Servers uses one HP ProCurve Switch 2626
for the management network. Configurations with between 12 and 22 Object Storage Servers
require a second HP ProCurve Switch 2626 for the management network. A third HP ProCurve
Switch 2626 is required for larger configurations of between 24 and 32 Object Storage Servers.

1.2.2 HP SFS for HP SFS20 Enclosure Building Blocks

In an HP SFS for HP SFS20 Enclosure configuration, the number of Object Storage Servers that
can be installed in a cabinet depend on the type of server (DL360 or DL380) and on the ratio of
HP SFS20 Enclosures to servers.
For example, a building block with a 1:1 ratio of HP SFS20 Enclosures to ProLiant DL360 servers
requires 6U of cabinet space (2U for the two DL360s, and 4U for the two HP SFS20 Enclosures).
The same building block using ProLiant DL380 servers requires 8U of cabinet space (4U for the
two DL380s, and 4U for the two HP SFS20 Enclosures). A ProLiant DL360 4:1 building block
needs 18U, whereas a ProLiant DL380 4:1 building block requires 20U of cabinet space.
Table 1-3 and
varying ratios. The base rack is always configured to allow a 2:1 ratio of HP SFS20 Enclosures
to MDS and administration servers.
