Attaching Your Cluster Shared Storage System in a DirectAttach 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. Table 1-3. Direct-Attached Clusters Rules and Guidelines Rule/Guideline Primary storage Fibre Channel HBAs Emulex driver version QLogic driver version Operating system Dell | EMC CX600 core software 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. 8 Platform Guide
