EXP5060 storage expansion enclosures
Options:
v FlashCopy
v VolumeCopy
v Enhanced Remote Mirroring
Clustering support
Clustering is a means of sharing array groups among controllers to provide
redundancy of controllers and servers. This redundancy is important if a hardware
component fails. If a hardware component failure occurs in a cluster, another server
takes ownership of the array group.
Clustering requires software specific to your operating system. For more information
about clustering, see www.ibm.com/servers/storage/disk/ds4000/interop-matrix.html.
Inventory checklist
After you unpack the DS5100 and DS5300, verify that you have the following items.
See “Storage subsystem components” on page 6 for the locations of hardware
components on the DS5100 and DS5300.
