• Communication between the Servers and the External Storage Box
The communication between the two cluster nodes and the external storage box takes place via shared
SCSI bus. DIGITAL Server Cluster Kits include two Adaptec 2944UW ultra wide SCSI adapters,
which also support the non-ultra cabinets. Each kit contains two, 5M wide-differential SCSI cables to
create these communication links. Also included are Y cables and a differential SCSI terminator for
external termination of all elements on the SCSI bus. The Y cable allows for the easy removal and
replacement of a failed server without affecting the uptime of the cluster and its users.
• Private Network Connection between Cluster Nodes
Although the two cluster nodes can communicate over the LAN, a private network connection
between the nodes is utilized for redundancy, allowing the cluster nodes to continue communications
in the event of LAN failure. This removes the possibility of unnecessary failovers due to network
problems. The DIGITAL Server Cluster Kits include two FR-DE500-BA 100/10Mbit PCI 10BaseT
Ethernet controllers. A crossover twisted pair cable is also provided to complete the connection.
• Software
DIGITAL Server Cluster Kits, which support both DCNT and MSCS, include the following software:
