Attaching Your Cluster Shared Storage System in a Direct-
Attach Configuration
This section provides the rules and guidelines for attaching your NAS cluster nodes to the shared
storage system using a direct connection (without Fibre Channel switches).
In a direct-attach configuration, both cluster nodes are connected directly to the storage system.
Rules and Guidelines
The following rules and guidelines described in Table 1-3 apply to direct-attached clusters.

PCI Buses
PCI/PCI-X bus 1: PCI slot 1 is
64 bit, 33/66/100 MHz.
PCI/PCI-X bus 1: PCI slot 2 is
64 bit, 33/66/100/133 MHz.
PCI/PCI-X bus 2: PCI slot 3 is
64 bit, 33/66/100/133 MHz.
NOTE:
PCI/PCI-X slot 1 must be
empty for PCI/PCI-X slot 2 to
attain an operating speed of
133 MHz.
Description
Each cluster can support up to 22 unique drive letters for shared
logical drives.
Only one storage system can be direct-attached to the cluster.
Emulex LP9002L, Emulex LP982 or LP9802, or QLogic QLA2340.
Storport miniport driver 5-1.00a15 or later.
Storport miniport driver 8.2.2.20 or later.
Each direct-attached cluster must run Windows Storage Server 2003,
Enterprise Edition.
2.04.0 or later; however, version 2.04.1 (EMC Access Logix™ enabled)
or later is required if two clusters or a mix of clustered and
nonclustered hosts are direct-attached to the CX600.

HBA
For dual HBA
configurations, Dell
recommends installing the
HBAs on separate PCI buses
to balance the load on the
system.
RAID Controller
Install in any
available PCI slot,
or use the
integrated RAID
controller on the
system board.
