Internet Small Computer Systems Interface or iSCSI (/ aɪ ˈ s k ʌ z i / ⓘ eye-SKUZ-ee) is an Internet Protocol-based storage networking standard for linking data storage facilities. iSCSI provides block-level access to storage devices by carrying SCSI commands over a TCP/IP network. iSCSI facilitates data transfers over intranets and to manage storage over long distances.
The Nimble CS-Series iSCSI and Fibre Channel storage array has 4 product lines for data centers available in each CS-Series. The product lines are CS200, CS300, CS500, and CS700 and combine both HDDs with SSDs in a hybrid fashion. In August 2016, Nimble Storage updated their CS-Series arrays to the following: CS1000/H, CS3000, CS5000, and CS7000.
An iSCSI target is a storage resource located on an iSCSI server (more generally, one of potentially many instances of iSCSI storage nodes running on that server) as a "target". An iSCSI target usually represents hard disk storage, often accessed using an Ethernet -based network.
The drives within an A-unit and all other drives in a string had interfaces similar to the early interfaces, above. A-units connected to IBM Directors or integrated attachments . Small Computer System Interface (SCSI) , originally named SASI for Shugart Associates System Interface, is an early (circa 1978) industry standard interface explicitly ...
PowerVault is a line of data storage and backup products formerly from Dell, and currently for Dell EMC.. After Dell acquired EqualLogic for its iSCSI products in 2008, and Compellent Technologies in 2011, the PowerVault line was positioned as less expensive than the other product lines.
With iSER the target drives all data transfer (with the exception of iSCSI unsolicited data) by issuing RDMA write/read operations, respectively. When the iSCSI layer issues an iSCSI command PDU, it calls the Send_Control primitive, which is part of the DI. The Send_Control primitive sends the STag with the PDU.
