Kool Tools: ATTO Technology 40Gb Ethernet to 12Gb SAS storage controllers
ATTO Technology’s (www.atto.com) ATTO XstreamCORE ET 8200 storage controller is a top-of-rack controller with base functionality of a high performing protocol bridge that enables multiple client servers to remotely access and share any SAS storage over Ethernet with less than 2 microseconds of added latency.
It combines the parallel processing capabilities of ATTO developed chipsets which include xCORE™ Data Acceleration technology with multiple parallel I/O acceleration engines to move data at an extremely fast rate and the lossless RDMA Ethernet protocol iSER (iSCSI Extensions for RDMA) which then integrate with your SSD or HDD based JBOD storage to create a high bandwidth shared storage solution. With the ability to scale up using any brand of storage or enclosure,
XstreamCORE is ideal for high performance and large capacity use cases, including storage disaggregation, hyperscale data centers fast block storage, high performance computing and imaging, databases and financial applications. The 8200 is the Ethernet version of the centralized, rack-scale flash storage controller that shares and remotely connects up to 960 SAS SSD or HDD drives. XstreamCORE ET 8200 converts 12Gb and 6Gb SAS/SATA storage to 40Gb Ethernet allowing direct attached JBOD or JBOF storage to be remotely accessed by any authorized user.
XstreamCORE then remotely shares this storage over long or short distances using high-speed iSER Ethernet technology. iSER extends iSCSI by eliminating TCP/IP processing overhead and instead uses RDMA to access memory directly without going through the CPU to transport iSCSI commands which preserves interoperability of the iSCSI protocol.
XstreamCORE ET 8200 is the third controller in the XstreamCORE family which introduces Ethernet and complements ATTO Fibre Channel based controller models. Designed for highly reliable installations, XstreamCORE has redundant, field replaceable power supplies, allows independent scaling of storage and compute and enables use lower cost SAS/SATA drives and enclosures to be shared over Ethernet networks.
