Advanced functions for HDS Thunder, Hitachi AMS 200, AMS 500, and AMS 1000, WMS100, and HDS TagmaStore WMS

Some advanced functions of the HDS Thunder, Hitachi AMS 200, AMS 500, and AMS 1000, WMS100, and HDS TagmaStore Workgroup Modular Storage (WMS) systems are not supported by Lenovo Storage V series clustered systems.

Advanced copy functions

Advanced copy functions for HDS Thunder, Hitachi AMS 200, AMS 500, and AMS 1000, WMS100, and HDS TagmaStore WMS systems are not supported for disks that are managed by Lenovo Storage V series systems because the copy function does not extend to the Lenovo Storage V series cache. For example, ShadowImage, TrueCopy, and HiCopy are not supported.

LUN Security

LUN Security enables LUN masking by the worldwide node name (WWNN) of the initiator port. This function is not supported for logical units (LUs) that are used by Lenovo Storage V series systems.

Partitioning

Partitioning splits a RAID into up to 128 smaller LUs, each of which serves as an independent disk-like entity. The Lenovo Storage V series system and HDS Thunder, Hitachi AMS 200, AMS 500, and AMS 1000, WMS100, and HDS TagmaStore WMS systems support the partitioning function.

Dynamic array expansion

The HDS Thunder, Hitachi AMS 200, AMS 500, and AMS 1000, WMS100, and HDS TagmaStore WMS systems allow the last LU that is defined in a RAID group to be expanded. This function is not supported when these storage systems are attached to the Lenovo Storage V series system. Do not perform dynamic array expansion on LUs that are in use by the Lenovo Storage V series system.

Note: Use in this context means that the LU has a LUN number that is associated with a Fibre Channel port, and this Fibre Channel port is contained in a switch zone that also contains Lenovo Storage V seriesFibre Channel ports.

Host storage domains and virtual Fibre Channel ports

The HDS Thunder 95xxV, Hitachi AMS 200, AMS 500, and AMS 1000, WMS100, and HDS TagmaStore WMS systems support host storage domains (HSD) and virtual Fibre Channel ports. Each Fibre Channel port can support multiple HSDs. Each host in a given HSD is presented with a virtual target port and a unique set of LUNs.

The Thunder 9200 does not support HSD and virtual Fibre Channel the ports.
