Compaq DIGITAL Server Cluster Kits for Windows NT manual ∙ Disk Drives, Capacity, Part Number

37

DCNT solution allows for dual active server operation, it is recommended that both servers be capable of handling the combined workloads of the two servers, as would occur during a failover operation. This should be taken into account when determining which servers are clustered together. For example, a DIGITAL Server 1200 handling file/print services should not be paired with a DIGITAL Server 7100 database server, handling near-capacity workloads.

Each server must have at least one internal hard disk. This disk is required for the installation of the operating system, cluster, and application software. However, this disk is not part of the shared storage, so it cannot be failed over.

Neither DCNT nor MSCS support mixed architecture (Intel and Alpha) in the same cluster.

∙Disk Drives

Drives must be ordered separately.

Note: The drives for the DIGITAL Servers and the DIGITAL Server Cluster Kits are different. The drives differ in capacity, geometry and firmware levels, and are not interchangeable. These drives are not supported in the system or in the BA356 stand-alone. They are supported in all Cluster Kits (including the BA356 Cluster Kit). They are not supported anywhere connected to the FR-PCTAR (Mylex) controllers.

For DIGITAL Server Cluster Kits, supported drives include:

∙LAN Network Connection

For the cluster to provide services to its clients, both servers and clients must be on a LAN. These guidelines assume that the components required for this are already in place, for example Network
