MAC address vendor

3ware, Inc. MAC Prefix: Device Type Unknown

Primary prefix
00:05:0E
Block
MA-L

Summary

// what this is
3ware is registered to MAC prefix 00:05:0E in the IEEE OUI database. When a device's MAC address begins with 00:05:0E, that block was registered by 3ware — the OUI identifies the maker of the network hardware, which is not always the brand on the device.

A MAC address beginning 00:05:0E is registered to 3ware, Inc.; the available evidence does not identify a device type for this prefix. A match establishes a registry assignment, not the maker of a particular device, its operating system, present ownership, or security status.

The IEEE record lists one MA-L assignment, 00:05:0E, with a 24-bit prefix and 24 bits remaining. The first byte is 00: its Group bit is 0 and its Local bit is 0. Those bits are fixed for an exact prefix match; changing either produces a different prefix. RFC 7042 explains the Group and Local bits and MAC prefix structure.

A 24-bit suffix allows 16,777,216 possible values. That is the address space available under the prefix, not a count of devices, shipments, or addresses observed in use. The IEEE CSV record does not display an assignment date.

A 2004 AMCC release described 3ware as a provider of SATA RAID storage solutions for backup, near-line storage, NAS, video, and high-performance computing, and described its StorSwitch architecture. It announced an agreement for AMCC to acquire 3ware, subject to closing conditions and regulatory approvals; this announcement alone does not establish completion or current corporate status. The release does not map these products to this MAC prefix.
