Hardware Requirements

Data Routers and Network Storage Routers
The Compaq Fibre Channel Tape Controller, Modular Data Router (MDR), and Network Storage Router (NSR) are Fibre Channel-to-SCSI bridges that allow a SCSI tape device to communicate with other devices on a Fibre Channel. Tapes and tape libraries supported by the MDR or NSR are supported for use in a TruCluster when deployed on the MDR or NSR.

The following tape controllers and modular data routers are supported on shared storage:

• 340654-001 Fibre Channel Tape Controller
• 152975-001 Fibre Channel Tape Controller II
• 163082-B21 3R-A2673-AA Fibre Channel Modular Data Router (MDR)
• 163083-B21 3R-A2774-AA Fibre Channel Modular Data Router (MDR)
• 218240-B21 3R-A3292-AA Fibre Channel Modular Data Router (MDR)
• 218241-B21 3R-A3312-AA Fibre Channel Modular Data Router (MDR)
• 280823-B21 (3R-A3747-AA) Network Storage Router (N1200) ¹
• 262672-B21 (3R-A3746-AA) Network Storage Router (E1200) ¹
• 286694-B21 (3R-A3871-AA) Network Storage Router (E1200) ¹
• 262665-B21 (3R-A3935-AA) Network Storage Router (E2400) ¹
• 262664-B21 (3R-A3745-AA) Network Storage Router (E2400) ¹
• 262653-B21 (3R-A3740-AA) Network Storage Router (M2402)¹
• 262654-B21 (3R-A3741-AA) Network Storage Router (M2402)¹

¹ Note that TruCluster support for tape libraries with N1200, E1200, E2400, and M2402 is restricted to DLT and SDLT based libraries only, i.e. MSL5026SL/DLX, ESL9198SL/DLX, and ESL9326SL/DL/DLX.

Features –TruCluster Server V5.1

Support for Memory Channel API

Note to users of the Memory Channel application programming interface (MC API) with Memory Channel virtual hub (vhub) configuration:
The Memory Channel API is not supported for data transfers larger than 8K bytes when loopback mode is enabled in two member clusters configured with MC virtual hub. For more information on loopback mode go to http://www.tru64unix.compaq.com/docs/updates/TCR51A/TITLE.HTM and refer to the 21.Mar.2002 Technical Update titled "MC API Applications May Not Use Transfers Larger Than 8 KB with Loopback Mode Enabled on Clusters Utilizing Virtual Hubs".

Optional Software

SANworks™ Data Replication Manager by Compaq

SANworks Data Replication Manager (DRM) is controller-based data replication software for disaster tolerance and data movement solutions. DRM works with the new StorageWorksä Fibre Channel MA8000 /EMA12000 Storage Solutions by Compaq. The RAID Array 8000 (RA8000) and Enterprise Storage Array 12000 (ESA12000) are also supported.

Multiple clusters or standalone systems can be connected using DRM to replicate application data. DRM within a single cluster is supported only through Custom Special Systems' "Campus-Wide Disaster Tolerant Cluster" product offering.

For more information about DRM, see the SANworks Data Replication Manager QuickSpec. For more information about the Campus-Wide DisasterTolerant Product, see http://www.compaq.com/solutions/customsystems/ha/tru64_campus_clusters.html.
