Hitachi MP-96RD625-01 manual Requirements and Restrictions for URz, System Requirements

Requirements and Restrictions for URz

URz has the following requirements and restrictions:

•System requirements (see the next section)

•Disk track format

•One-to-one volume copy operations

•Duplicate VOLSER

•Volume type

•Journal group

•Accessing URz primary data volumes and secondary data volumes

•Cache and NVS

•Duplicate volume

System Requirements

URz operations involve the USP V primary storage systems and secondary storage systems containing the primary and secondary data volumes, the remote copy connections between the primary storage systems and secondary storage systems, the host(s) at the primary and secondary sites, and the licensed URz remote console software. The URz system requirements are:

•primary storage system: USP V storage system with URz installed.

•secondary storage system: USP V storage system with URz installed.

Note: URz can coexist with UR in the same USP V storage system.

Note: The remote copy connection with the NAS interface is not supported.

•Remote copy connections – fibre channel (see section Setting up Remote Copy Connections):

•Multimode or single-mode optical fibre cables are required at both the primary storage system and secondary storage system.

•For distance up to 0.5 km, multimode optical shortwave fiber cables are required between the primary storage system and secondary storage system.

•For distances from 0.5 km to 1.5 km (1,640 to 4,920 feet), multimode shortwave fibre-channel interface cables with up to two switches are required.

•For distance up to 10 km, single optical long wave fiber cables are required between the primary storage system and secondary storage system.

•For distances from 10 km to 30 km (6.2 to 18.6 miles), single-mode long wave fibre-channel interface cables with up to two switches are required.
