SAS Disk Enclosure
The SAS disk enclosure is a rack-mounted disk enclosure and is part of some NonStop
BladeSystem configurations. The SAS disk enclosure supports up to 25 SAS disk drives, 3Gbps
SAS protocol, and a dual SAS domain from Storage CLIMs to dual port SAS disk drives. The
SAS disk enclosure supports connections to SAS disk drives. Connections to FCDMs are not
supported. For more information about the SAS disk enclosure, see the manual for your SAS
disk enclosure model (for example, the HP StorageWorks 70 Modular Smart Array Enclosure
Maintenance and Service Guide).
The SAS disk enclosure contains:
• 25, 2.5” disk drive slots with size options:
— 72GB, 15K rpm
— 146GB, 10K rpm
• Two independent I/O modules:
— SAS Domain A
— SAS Domain B
• Two fans
• Two power supplies
IOAM Enclosure
The IOAM enclosure is part of some NonStop BladeSystem configurations. The IOAM enclosure
uses Gigabit Ethernet 4-port ServerNet adapters (G4SAs) for networking connectivity and Fibre
Channel ServerNet adapters (FCSAs) for Fibre Channel connectivity between the system and
Fibre Channel disk modules (FCDMs), ESS, and Fibre Channel tape.
Fibre Channel Disk Module (FCDM)
The Fibre Channel disk module (FCDM) is a rack-mounted enclosure that can only be used with
NonStop BladeSystems that have IOAM enclosures. The FCDM connects to to an FCSA in an
IOAM enclosure and contains:
• Up to 14 Fibre Channel arbitrated loop disk drives (enclosure front)
• Environmental monitoring unit (EMU) (enclosure rear)
• Two fans and two power supplies
• Fibre Channel arbitrated loop (FC-AL) modules (enclosure rear)
You can daisy-chain together up to four FCDMs with 14 drives in each one.
Maintenance Switch
The HP ProCurve 2524 maintenance switch provides the communication between the NonStop
BladeSystem through the Onboard Administrator, c7000 enclosure interconnect Ethernet switch,
Storage and IP CLIMs, IOAM enclosures, the optional UPS, and the system console running HP
NonStop Open System Management (OSM). For a general description of the maintenance switch,
refer to the NonStop NS14000 Planning Guide. Details about the use or implementation of the
maintenance switch that are specific to a NonStop BladeSystem are presented here.
