RAID employs the technique of disk striping, which involves partitioning each
drive's storage space into units ranging from a sector (512 bytes) up to several
megabytes. The stripes of all the disks are interleaved and addressed in order.
RAID level The type of RAID implementation. RAID levels include RAID 0, RAID 1, RAID 2,
RAID 3, RAID 4, RAID 5 and RAID 6.
refresh To update the database using the most recent information.
resource group Resources grouped by storage system, parity group, LDEV ID, storage port, etc.
role Operation(s) permission that users in a user group have for resources in a resource
group.
SAN storage area network. A network of shared storage devices that contain disks
for storing data.
SCSI (Small
Computer System
Interface)
Standards that define I/O buses primarily intended for connecting storage systems
and devices to hosts through host bus adapters.
secondary volume After a backup, the volume in a copy pair that is the copy of the original data
on the primary volume (P-VOL). Recurring differential data updates keep the data
in the S-VOL consistent with the data in the P-VOL.
Secure Sockets
Layer (SSL)
A common protocol for managing the security of message transmission over the
Internet.
Two SSL-enabled peers use their private and public keys to establish a secure
communication session, with each peer encrypting transmitted data with a
randomly generated and agreed-upon symmetric key.
Smart Tiers (Smart) In addition to Thin Provisioning functionality, this functionality places data on a
tier according to the I/O load. A data area that has a high I/O load is placed
in a high-speed hardware tier, and a data area that has a low I/O load is placed
in a low-speed hardware tier.
This document refers to the storage area that is created by using Smart as a
Smart pool, an actual volume that is one of the volumes making up a Smart pool
as a Smart pool volume, and a virtual volume that is created by a Smart pool
as a Smart volume.
SNMP Simple Network Management Protocol
Thin Provisioning
(THP)
Functionality that allocates virtual volumes to a host, and uses the physical
capacity this is necessary according to the data write request.
This manual refers to the storage area that is created by using THP as a THP
pool, an actual volume that is one of the volumes making up a THP pool as a
THP pool volume, and a virtual volume that is created by a THP pool as a THP
volume.
THP/Smart pool An area where THP/Smart pool volumes (actual volumes) are registered. When
a THP/Smart volume (virtual volume) has a write operation from a host, that data
is stored in a THP/Smart pool volume.
THP/Smartpool
volume
An actual volume that is one of the volumes making up a THP/Smart pool.
