Determine M5214 Disk Enclosure vs. M5314

[Adam Garsha]

1.) M5214 does not support FATA near-online drives correct?

2.) How can I tell if I have M5214 or M5314 disk enclosures?

1) I've never heard about that. A FATA drive has a Fibre Channel interface, so I'd be very surprised if it did not.

2) Now, that's a good question. It should be visible by the product number, but that is mounted on the side of the enclosure and you have to pull it from the cabinet for inspection. If I understood it correctly, the difference is the I/O modules, but I don't have any low-level details, sorry.

I've heard conflicting information from HP.

1.) In "EVA SAN Management training" I learned that only M5314 supports FATA.

2.) When calling HP Storage support I heard that both M5214 and M5314 support FATA.

3.) When querying my Storage Account Specialist (whom I trust more then general support), I heard that M5314 is required.

M5314 has copper back-end. M5214 (the older EVA5000's) have optical back-end.

I've read somewhere that there are also M5114 around which have been used in early EVA-3000 supporting only copper cables while the M5214 was used in EVA-5000 and required SFPs. The M5314 are supposed to support both, copper cables and SFPs.

Well, turns out you that M5214 originally was not going to support FATA, but decision was made to allow it and support it.

So final word is M5214 and M5314 both support FATA. Seems to work.
