Storage Area Network
Storage Area Network
Our aging NAS setup based on a Linux NFS system needed to be replaced. After
extensive research of the traditional fibre-channel and iSCSI solutions, we
elected to go with the flexibility of Coraid's ATA over Ethernet (AOE).
Overview
Our Coraid SR1520, SR2421, and SRX3200 storage shelves sit on a private LAN,
providing AoE LUNs to servers across the enterprise. Most servers make use of
raw AoE LUNs directly. For some special storage needs, volumes are wrapped up
into a Linux "sanbox" appliance that can manage, aggregate, and re-export
storage over a variety of protocols. "Network RAID" is also possible,
mirroring data between shelves.
Usage
The flexibility, security, and performance of the AoE scales directly with the
Ethernet network. AoE is used across the enterprise in a variety of ways:
- E-Mail: Mailstores stored on XFS on LVM on RAID10 LUNs
- File Storage: User home directories and administrative shares on XFS on LVM
- Web Presence: Campus web sites on NFS on XFS on LVM
- Database Files: Tier 1 database storage on OCFS across shelves
- Disk Backup: Snapsync to remote storage permitting user-serviceable backups
- Virtualization: VM images stored on RAID1 SAS LUNs
- Etc., etc., etc.
We have run the gamut of Coraid devices: SR1520, SR1521, SR2421, SRX3200.
