storage

[′stȯr·ij]
(computer science)
Any device that can accept, retain, and read back one or more times; the means of storing data may be chemical, electrical, magnetic, mechanical, or sonic.

storage

The permanent holding place for digital data, until purposely erased. Storage is a repository that retains its content without power and includes magnetic disks, solid state drives (SSDs) and flash drives. The chips in these devices are said to be "non-volatile." Rewritable CD, DVD and Blu-ray discs, as well as magnetic tapes, are also non-volatile storage.

Storage specifically excludes the computer's main memory. Main memory, comprised of DRAM and SRAM chips, is a temporary workspace for executing instructions and processing data. These RAM chips do not hold their content when the power is turned off. Memory chips are "volatile."

Storage vs. Memory - More Confusing All the Time
Over the years, some vendors referred to disks and tapes as "memory" products, which blurs the distinction between storage and memory (RAM). To further confuse things, the flash "memory" chips in memory cards, solid state drives (SSDs) and USB drives are, in fact, storage chips that hold their content without power. See storage vs. memory, memory, dynamic RAM and static RAM. For summaries of all storage technologies, see magnetic disk, magnetic tape and optical disc.


They're All Chips, But...
The RAM chips (top) and the storage chips (bottom) in a USB drive and CompactFlash card (cases are removed) may look alike, but RAM chips are fast and volatile, while storage chips are slower and non-volatile. See memory module, USB drive and CompactFlash.







Storage Evolution
In the early 1990s, this 670MB multi-platter hard drive weighed 17 pounds including its case. By 2006, a half-ounce Microdrive (center) had 12 times as much storage on a single platter the size of a quarter. The solid state microSD card (right) weighs half a gram. See hard disk and Microdrive.

It also ensures proper order of SCSI commands and data to and from the server file system to the iSCSI storage target.
For example, if there were two iSCSI storage targets being used by the server, then there would be one initiator with two sessions running.
The connection layer is the TCP/IP connection between the server and the iSCSI storage target, which, in our case, is the ISCSI intelligent storage switch.
Because the iSCSI session is aware of alternate TCP/IP paths to the iSCSI storage target, it will automatically transfer traffic through an alternate TCP/IP connection.
To demonstrate how iSCSI failover functions, several companies participated in a third party demonstration where 5 videos where streamed from 5 iSCSI storage targets on an ISCSI intelligent storage switch to 5 Microsoft Windows 2003 hosts.
We were able to do video streaming to 5 hosts running iSCSI (wireless) going to an access point, then to a hub, then to the iSCSI intelligent storage switch (iSCSI to FCP-SCSI), then to a core-edge FC fabric, then to a virtual port, and finally mapped to an FC open-9 LUN on our enterprise class storage system.
