T5 Offloaded iSCSI with T10-DIX
ثبت نشده
چکیده
Executive Summary There are many sources of data integrity errors within storage networks and devices. The T10 (SCSI) standards committee developed the Data Integrity Field specification (DIF) to provide protection within storage disks by extending the size of disk sectors by 8 bytes, which contain protection information, including a 16 bit CRC. This integrity metadata enables corrupted write and read requests to be detected and the requests aborted and retried, thereby preventing silent data corruption and providing recovery options. The T10-DIF protection domain can be contained to the disk level, or extended to the storage network controller (HBA), covering the SAN interconnect.

متن کاملSmall Computer Systems Interface (SCSI) Command Ordering Considerations with iSCSI
Internet Small Computer Systems Interface (iSCSI) is a Small Computer Systems Interface (SCSI) transport protocol designed to run on top of TCP. The iSCSI session abstraction is equivalent to the classic SCSI "I_T nexus", which represents the logical relationship between an Initiator and a Target (I and T) required in order to communicate via the SCSI family of protocols. The iSCSI session prov...

Executive Summary The iSCSI Extensions for RDMA (iSER) protocol is a translation layer for operating iSCSI over RDMA transports, such as iWARP/Ethernet or InfiniBand. This paper presents iSER performance results comparing iWARP RDMA over 40Gb Ethernet and FDR InfiniBand (IB). The results demonstrate that iSER over Chelsio’s iWARP RDMA adapters achieves consistently superior results in throughpu...
