Raid Controllers
Hardware raid controllers disconnect timeout value may vary from vendor to vendor. TLER should trigger before the controller times out the drive. For example,
- 3ware 9650SE: 20 seconds
- LSI Logic(for IBM x-series): 10 seconds (see BIOS Raid Config Utility > Advanced Device Properties)
Note:
- Intel Matrix RAID / Intel Rapid Storage Technology embedded in Intel server motherboards and modern desktop motherboards is a pseudo-hardware controller, not real hardware raid.

Famous quotes containing the word raid:
“John Brown and Giuseppe Garibaldi were contemporaries not solely in the matter of time; their endeavors as liberators link their names where other likeness is absent; and the peaks of their careers were reached almost simultaneously: the Harper’s Ferry Raid occurred in 1859, the raid on Sicily in the following year. Both events, however differing in character, were equally quixotic.”
—John Cournos (1881–1956)
