Tech Specs

The secret to Coraid performance is in the protocol: ATA-over-Ethernet (AoE). This lightweight, secure protocol allows hardware to perform at maximum capacity by sitting directly on top of the Ethernet layer. Because it’s not “routed,” there’s no need for bulky IP, TCP, or iSCSI layers to slow down your data.

Just like the ATA-over-Ethernet protocol, Coraid code is more lightweight and streamlined than the typical storage software appliance. This is no accident. Bugs hide in lines of code. Fewer lines mean fewer bugs. Fewer lines simply execute faster.

The Coraid kernel is only 20,000 lines. A similar program in Linux is 20 million lines. The Coraid development team prides itself in writing negative lines of code, which is how a Coraid SRX stayed in production for 1,324 days without a reboot.

Mix and match SSD, SAS, and SATA, including 4K Advanced Format and NVMe.

Unlimited capacity dictated by disk choice.

JBOD or RAID 0, 1, 5, 6, or 10 with multiple automatic global spares.

1G or 10G SFP+, CX4, and twisted pair NIC options.

Command Line Interface enables simple provisioning, configuration, and monitoring.

No TCP/IP overhead.

Unlimited scale-out storage capacity and IOPS performance.

Supported natively in Linux kernel since 2005.

VMware HBAs are available.

10x price and performance advantage over Fibre Channel and iSCSI.

Hardware

There are three kinds of hardware in a datacenter: switches, servers, and storage arrays. Thanks to standardization, the components in storage arrays all work in a similar way. Although motherboards, disk controllers, and Ethernet interface cards vary in performance, the way they all work is still very much similar.

Because of this standardization, Coraid software can easily manage a range of storage arrays by supporting LSI storage adapters, Intel Ethernet NICs, and Intel processors. Companies like Supermicro make dozens of boxes that are Coraid appliance compatible.

The modern data center requires flexibility because data is not created equally: cold storage doesn’t require the same performance as production data. Through software-only Coraid appliances and commodity hardware manufacturers, your hardware will be tailored to your specific storage needs.
