HP Superdome 2 Partitioning Administrator Guide (5900-2064, November 2011)

Local Boot
Up to 4 boot paths are supported per P2000 FC G3 array.
• P2000 FC G3 array can support up to two dual port array controllers
• Each controller supports up to two 8GB FC links
Considerations for Local Boot
• Minimum configuration
One P2000 FC G3 can handle up to 4 partitions◦
◦ Boot paths are not redundant
– You must shutdown HP Superdome 2 to update P2000 FC G3 firmware.
• Optimal configuration
◦ Create redundant boot paths to separate dual controllers on the P2000 FC G3
– Would support only two partitions per array
Boot from local SAN
• HP Fibre Channel Switch(s)
HP StorageWorks 8/24 Base SAN Switch (AM868A) is the default switch◦
◦ 8GB switches recommended
• Considerations for Local SAN
Minimum configuration:
– For 16 or less partitions, one dual controller P2000 can be used
◦
◦ Optimal configuration (Redundant boot paths)
– Array must be configured to expose both the P2000 controllers to the partitions to
allow P2000 firmware updates
– The boot paths must be in separate switches and P2000 controllers.
– Dual path connectivity allows the switch or array firmware updates without bringing
SD2 down
– For more redundancy or >16 partitions a second P2000 can be used
Boot from External SAN
An unlimited number of LUNs might be presented by an external SAN.
