Coraid, Inc. is a computer data storage vendor that provides storage area network (SAN) products that use Ethernet, headquartered in Redwood City, California.[1]

Company history[edit]

The company was founded by Brantley Coile, who previously created the Cisco PIX firewall and Cisco LocalDirector products.[2] Coile began the research and development phase of the company in 2000 after leaving Cisco Systems, and developed the ATA over Ethernet (AoE) protocol, which enables storage networking using raw Ethernet frames for transport.

The company began selling its EtherDrive family of storage arrays in 2004. The open AoE protocol was released to the Linux community, and has been included in the Linux kernel since 2005,[3][4] starting with version 2.6.11.

Coraid is backed with a total of $85M in funding. The company received a first, $10M round of institutional financing from two venture capital funds in January 2010,[5][6] at the same time introducing new management and an advisory board. The company also moved its headquarters to Redwood City, CA early in 2010. Coraid secured an additional $25 million in Series B funding in November 2010, followed by a third round of $50M in November 2011.[7]

The company website says they have more than 1,700 customers in sectors including media, hosting service providers, telecommunications, healthcare, aerospace, manufacturing, and government.[8]

EtherDrive and EtherFlash storage[edit]

AoE is a second generation SAN transport protocol using layer 2 of the OSI model of network communications, "raw Ethernet." A key advantage of the protocol is the ability to use standard Ethernet networks and a simple yet efficient protocol that minimizes packet size. Coraid designs both hard disk drive and solid-state drive flash storage arrays.[9]

Coraid markets EtherDrive and EtherFlash as a "scale-out architecture", delivering low-latency access and offering up to several petabytes of storage. The company's products compete with Fibre Channel and iSCSI products using block-based storage.

Block storage for OpenStack is supported within Cinder.


A Coraid EtherDrive storage cluster (SAN)

Introduced in 2012, the ZX line of appliances provides a ZFS NAS interface to EtherDrive storage. The ZX-Series appliances provides Ethernet SAN performance together with advanced features supported by Oracle's file system, including high availability, deduplication, snapshots and copy-on-write clones, and continuous integrity checking with automatic repair and high scalability.[citation needed]


A Software Defined Storage platform, EtherCloud enables one-click provisioning and automation of enterprise-class SAN and NAS storage, as well as REST APIs for integration into OpenStack and the network, server, virtualization and application layers.

Coraid also supports VMware ESX environments.[10]
