Simple, fast fabric connectivity to any storage

ATTO XstreamCORE® storage controllers are high-performance accelerated protocol conversion appliances that add shared storage benefits to SAS storage but at direct attached speeds.

Designed for Increased Flexibility

ATTO XstreamCORE is a solid state appliance that connects SAS SSD and Hard Drive solutions using standard JBODs, JBOFs or RAID arrays to Ethernet or Fibre Channel networks. Attach up to 960 total drives to multiple servers and assign drives on a drive by drive basis to one or many servers.

Simplified Management

Manage storage through in-band or out-of-band methods for flexibility and integration with most server-side software plus features such as ATTO Drive Map Director™ provide reliable, static storage configurations ensuring that operating costs are kept low and complexity is not a part of the solution

Move Data. Faster.

Designed to push the limits on performance, XstreamCORE utilizes exclusive ATTO eCORE™and xCORE™ technologies to deliver up to 1.2M 4K IOPS or 6.4GB/s throughput per controller with extremely low latency.

Build a Cost Effective Infrastructure

ATTO XstreamCORE allows you to disaggregate storage from compute resources thus eliminating the expense of more servers and additional software licensing fees.  With a performance footprint that drives full racks of storage, it doesn’t take long before you become a hero for saving significant budget dollars.

Get longer life out of existing SAS Direct Attached Storage

When you have isolated SAS storage silos, XstreamCORE connects this stranded storage to shared Ethernet or Fibre Channel SANs allowing greater flexibility and usefulness. Even if there is no SAN installed the benefits that XstreamCORE will add are enormous including the ability to increase the speed at which live migration of virtual machines take between physical server hosts.
