HP StorageWorks Enterprise Modular Library E-Series User Guide (AH876-96001, September 2007)

•
Library robotics c ontroller (see Figure 8 on page 25)—A single slot, 6U-wide cPCI boa rd having
Ethernet ports and an RS-232 port. One Ethernet port connects this controller to the Interface
Manager card.
•
HP StorageWorks Interface M anager card (see Figure 9 on page 26)—A single slot, 4U-wide
cPCI board having six Ethernet ports. This board contains 128MB of dynamic random access
memory (DRAM ) plus a 256MB CompactFlash memory card, both in their own sockets. A
2U-wide adapter panel next to the 4U-wide Interface Mana ger card allows it to fitinthelowest
6U-wide card cage slot.
• Interface controller—A cPCI board, having two FC ports for connecting to the SAN, along with
four FC ports for connecting up to four HP LTO2 or LTO3 tape drives. LTO4 tape drives do
not connect to the interface controller; instead, they connect directly to the SAN. The interface
controller is available in two speeds. The HP StorageWorks e2400-FC 2Gb interface controller
has an FC speed of 2 Gbps, is 6U wide, and uses a single slot (see Figure 10 on page 27). The
HP StorageWorks e2400-FC 4Gb i nterface controller has an FC speed of 4 Gbps, is 4U wide,
andusestwoslots(seeFigure 11 on page 27).

The c
able management feature is a spool, mounted near the tape drives, that allows LAN and FC cables
to be
dressed and routed away from hot plug or hot swap components.
Expansion modules
Three expansion modules are available to increase library capacity beyond that provided by the base
module. These expansions modules are:
• Tape drive expansion module
• Card cage expansion module
• Capacity expansion module
