c7000 A/B bays?

[akopylov]

Good day. I apologize in advance for my bad English.

Im totally new to HP and Im currently reading OA user guide. And I got question about deivce bays 1A, 1B etc. There are 16 bays that can carry 16 half-height/8 full-height single-wide/4 full-height dual-wide blades (dual-wide blades in my case). So what about this numeration is?

I know that there are sides A and B on dual-wide blades, but in EBIPA i just set iLO IPs for bays 2/4/6/8 and got access to iLO of all 4 dual-wide blades. Furthermore there is shown in power sequence settings that blades are placed in 2, 4, 6 and 8 bays, all other bays are subsumed. All double dense side A and double dense side B devices are "absent". So what these A/B ports need for?

The size of such blade server can be very different, from 2 servers in a single half height chassis (e.g.

HP ProLiant BL2x220c) up to 4 full height blades as a single server (e.g. BL860c i4). In first case the system will name them Bay1A or 1B etc.

Sorry, i cant get the logic.

Look at my screenshots.

It looks like there are 16 A ports and 16 B ports, 32 ports in total. But this enclosure can carry max 16 blades.

Yes, max 16 blades, but max. 32 servers, see above.

Ah, really there are two server nodes in one blade. But I never faced blades like that, how does it look like? I mean is there 2 iLO for 1 blade or what? Whats the point to divie single bay and make two nominal bays? I guess this doesnt affect interconnect port mapping somehow. Was it made for user rights delegating and power sequence setting purposes only? For example if I want to give operator rigths to user only for one server node in the 2node-blade?

>> But I never faced blades like that

Me too, but there are several models, 2 servers in a single chassis, IMHO both with ILO. You will see this in Enclosure Bay IP Addressin section of OA. They have a single NIC only, so each server goes to a single interconnect port. Really not HA, but a high server density per enclosure.

Thanks a lot. Now this thing about A/B bays is pretty clear for me.

I have faced the 2x220's.

It's 2 seperate servers in 1 chassis.

2 system I/O boards, each with ILo and internal HDD'.

They got seperate serial numbers and product numbers

A and B side is not the same prosuct number, nor same spare number on the system I/O board.

There's 2 sets of power button's, Status LED's and SUV(?) cables.

Adn seem, there's 2 embedded NIC's on both system I/O BD's.
