XstreamCORE ET 8200

40Gb/s Ethernet (2-Port) to SAS intelligent Bridges

Model No. XCET-8200-002

Model No: XCET-8200-TP2

ATTO XstreamCORE® intelligent bridges are high-performance accelerated protocol conversion appliances which add shared storage benefits to SAS storage but at direct attached speeds. XstreamCORE provides remote access to SAS storage enabling storage owners to disaggregate storage from server hardware using JBOD, JBOF, RAID or Tape Storage*. Use cases include mapping one or many individual drives to space limited rack or blade servers, remapping attached drives from failed servers to replacement servers, adding shared capabilities to direct attached storage and remotely locating direct attached disk or tape devices.

Optimized for high performance with multiple hardware acceleration engines, XstreamCORE provides industry-leading performance to up to 64 servers with less than 2 microseconds of added latency. XstreamCORE enables a common set of services and features and is engineered with an open design that does not alter the data path. ATTO intelligent bridges keep overall storage solutions flexible without locking users into proprietary hardware implementations. XstreamCORE is a modular building block with technology that allows SysAdmins to reduce resource load while decoupling storage from server resources.

*XCET-8200-TP2 supports Tape only

The XstreamCORE ET 8200 achieves up to 1.1M 4K IOPS and 6GB/s throughput per bridge with only 2 microseconds of added latency. XstreamCORE supports Extended Copy (LID1) data mover commands and will offload up to 5.2GB/s of data from CPU, memory, networks and storage fabrics leaving more resources for VMs and applications running on the host. Build solutions with up to 960 SAS SSD/HDD devices behind a pair of bridges and better manage, monitor and utilize this storage with current and future features built into XstreamCORE.

ATTO XstreamCORE intelligent bridges can be tuned for various applications that require common features and services for storage. Contact us to discuss development or co-development of services and features to tightly integrate with your solution. Embedded form factor is also available. (OEM only)
