iSCSI has been connecting storage solutions for decades and over the years manufacturers have been trying to make iSCSI more efficient with greater speed and lower latency. In theory it is possible to make iSCSI faster but in practical implementations manufacturers have been at the mercy of TCP/IP.  TCP/IP offload engines can be inefficient and running iSCSI in software would be extremely slow.

ATTO Technology is excited to announce our solution to this challenge: ATTO XstreamCORE® ET 8200 hardware accelerated protocol bridge. In XstreamCORE ET 8200, TCP/IP is implemented in hardware with only two microseconds of added latency.  This is the key to improved speed and efficiency for iSCSI.

XstreamCORE ET 8200 utilizes multiple parallel I/O acceleration engines which work together to move data at an extremely fast rate.  Combined with the lossless RDMA Ethernet protocol iSER (iSCSI Extensions for RDMA) and hardware accelerated iSCSI, XstreamCORE integrates with SAS storage to create high-performance shared Ethernet storage solutions. 

SAS LUNs attached to the ET 8200 are connected via four x4 12Gb SAS ports and mapped and presented via two 40Gb Ethernet ports as RDMA based ISER and/or iSCSI targets.  The SAS (and/or SATA) storage can be of any type and in any combination: JBODs, JBOFs, arrays of flash or spinning disk, and LTO tape.  This flexibility allows for re-purposing of older or unused storage hardware adding to ROI.

This evolution in our line of hardware accelerated bridges frees system architects from the typical server storage constraints, helps to reclaim and reuse hardware, contributes to dramatic performance increases system-wide, and provides long distance cluster connectivity all in one simple top-of-rack 1U box.
