About vdisks A vdisk is a "virtual" disk that is composed of one or more disks, and has the combined capacity of those disks. The number of disks that a vdisk can contain is determined by its RAID level. All - HP StorageWorks MSA2312fc | HP StorageWorks 2000 G2 Modular Smart Array referenc - Page 17
available disk. If no properly sized spares are available, reconstruction cannot start. About volumes A volume is a logical subdivision of a vdisk, and can be mapped to controller host ports hosts, in order to avoid security exposures.

apply access privileges to one or more of the host ports on either controller. To maximize performance, it is recommended to map a volume to at least one host port on the controller that owns it. To sustain I/O in the event of controller failure, it is recommended to map to at least one host port on - HP StorageWorks MSA2312fc | HP StorageWorks 2000 G2 Modular Smart Array referenc - Page 19
chunk is based on the chunk size used when you created the vdisk (the default is 64 KB). Non-RAID and RAID-1 vdisks are considered to have a stripe size of 64 KB. • Specific size options let you select an amount of data for all accesses.

volume. For example, if a single volume exists, this setting enables the controller to use nearly half the memory for read-ahead cache. Only use Maximum when disk volume. In addition, only a single copy-on-write operation is performed on the master volume. The storage system allows a maximum number - HP StorageWorks MSA2312fc | HP StorageWorks 2000 G2 Modular Smart Array referenc - Page 21
the same amount of space as the source volume, and is independent from an I/O perspective. Volume independence is a key distinction of a volume copy (versus a snapshot, which is a "virtual" copy and dependent on the source volume).
