Requirements
2-5
Setting Up and Starting a CX700 System
unequalized 1-meter cables are adequate. A DAE does not support
cables shorter than 1 meter or longer than 10 meters.
DAE2P enclosures use cables with HSSDC2 connectors on at least one end.
CX700 and DAE interconnections should maintain LCC consistency;
that is, one set of FC loops should connect the CX700’s SP A and each
DAE’s LCC A, and the other FC loops should connect the CX700’s
SP B and each DAE’s LCC B.
Do not leave an unused (that is, dangling) cable connected to any
Fibre Channel port because it may cause excess noise and
performance problems on the Fibre Channel.
Disk Requirements
CX700 storage systems require at least five Fibre Channel disk
modules installed in slots 0, 1, 2, 3 and 4 (the leftmost slots) of the first
DAE2/DAE2P. The first DAE is typically adjacent to and directly
above the CX700.
The disk modules in slots 0-4 of the first DAE (enclosure 0, loop 0) provide
recovery and mirrored boot capability and are preloaded according to their
slot assignment before shipment.
Do not move a preloaded 0-4 module
from
its assigned slot to another slot. Remove it only to replace the disk.
For details on DAE disks and their configuration, refer to the hardware
reference for your DAE.
CX700 Address Requirements
The CX700 SPs process
front-end
I/O from servers (hosts), and
back-end
communication between disks and the DAEs that contain
them. Each host bus adapter, storage processor, and disk requires a
unique identifier, or
address
.
◆
Front-end (FE) addressing requirements vary depending on the
environment. Fibre Channel
fabric
(sometimes called
fibre port)
configurations include a Fibre Channel switch between the
storage system and host bus adapters on connected servers. Fibre
loop (FC-AL) front ends connect directly to a server.
In a fabric environment, the switch assigns a unique fabric ID to
each host bus adapter (HBA) and storage processor. In
direct-attach configurations, the HBA and SP negotiate a default
arbitrated loop physical address (ALPA).
