Definition
Multipath I/O Device Specific Module. A component of Adaptec
Storage Manager that allows you to set up multiple redundant
physical paths between your iSCSI Storage Appliance and your
iSCSI Storage Hosts. In a multipath IP SAN, if one path fails, all IO
activity automatically switches over (fails over) to the remaining
path. A component of the Windows Support installation option in
Adaptec Storage Manager; must be installed on all iSCSI Storage
Hosts on your IP SAN if you want to create volume mirrors or a
multipath IP SAN. See also Windows Support.
Note Adaptec Storage Manager supports failover only. Load
balancing is not supported.
A unique number that identifies the subnet on which device, such
as your iSCSI Storage Appliance, resides.
A level of restricted user permission that doesn't allow full access
to all features of the iSCSI Storage Appliance.
A form of data protection used by some RAID levels to re-create
the data of a failed disk drive in a logical device. See also Two
disk drives, where one disk drive is a mirror of the other (the same
data is stored on each disk drive)..
Divides the space of a disk drive into isolated sections.
A physical storage devices such as a disk drive, tape drive, or
iSCSI Storage Appliance.
A pool is a disk drive or collection of disk drives which can be
divided into logical devices, which then become the iSCSI targets
that are accessed by the iSCSI initiators in your IP SAN systems.
Also known as a storage pool.
A component of Adaptec Storage Manager that automates
functions on iSCSI Storage Hosts such as volume and snapshot
creation. A component of the Windows Support installation option
in Adaptec Storage Manager; must be installed on all iSCSI
Storage Hosts on your IP SAN if you want to be able to provision
storage automatically and access other automated features. See
also Windows Support.
Redundant Array of Independent Disks.
Two or more disk drives with striped data (data distributed evenly
across the disk drives in equal-sized sections). RAID 0 does not
provide data protection.
Two disk drives, where one disk drive is a mirror of the other (the
same data is stored on each disk drive).
