XstreamCORE FC 7550

16Gb/s Fibre Channel (4-Port) to SAS Accelerated Storage Controller

Model No. XCFC-7550-004

ATTO XstreamCORE Storage Controllers 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 4 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 Storage Controllers keep overall storage solutions flexible without locking users into proprietary hardware implementations. The ATTO Storage Controller is a modular building block with technology that allows SysAdmins to reduce resource load while decoupling storage from server resources.


The XstreamCORE FC 7550 achieves up to 1.2M 4K IOPS or 6.4GB/s throughput per controller with only 4 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 240 SAS SSD/HDD devices behind a pair of controllers and better manage, monitor and utilize this storage with current and future features built into XstreamCORE.

ATTO XstreamCORE Storage Controllers 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)
