S8710 (Dual?) Power Supply & UPS

[Toni269]

I have S8710 servers A and B with CM3.0. They are also connected to UPS A and B. Is it possible to add a second power supply to each S8710 server and connect it to alternating UPS's?

I asked a BP and they said it wasn't a supported option. The failover to standby due to lack of power works perfectly, but I'm trying to avoid the failover with a 2nd power supply.

Thanks in advance for any info!

it's a standard HP Server, so I'm guessing you could just purchase a second power supply.

That's purely a guess however...

Let me know how this turns out Toni as I am considering the same thing here. It (to me at least) would make since to add a redundant power supply on the servers. It apparently makes since to the networking world as the servers do have a slot for a second power supply and most mission critical servers do have at least two power supplies.

I asked my BP about this, and they told me that you can order it that way from Avaya. I was going to do the same thing, but I was cautioned that I might mess up the maintenance if I didn't get it from Avaya.

I just got off the phone with HP technical support. After finally getting through the voice responce system (it's not designed for people here in the south ) He was able to find the servers through the SN on the side of the server. They said they would email me all the information he found on them, but I have not recieved it yet. If they do I will post. The PN he gave me for the power supplies is 313054-001.

I called another BP/GURU Engineer to ask and he said no, Avaya won't support it, he said it would void the Maintenance contract. Also I called Avaya Maintenance, spoke with someone who was very helpful, they didn't know and had to call me back. I did get a call back after a couple hours and they don't have any other customers doing it - they took the issue all the way up to Tier 3 and came back with "No" it's not supported. They also could not find that part number: 313054-001. I typed that Part number in HP search window and didn't find anything either. Then I shook my Magic 8 ball and it said: "All signs point to no."

Toni269,

The point is that you already have 2 redundant servers. It doesn't matter if a power supply (or a hard disk, you could also consider duplicating these) fails. What's your win in this case ?
The Avaya redundancy doesn't rely on duplicate power supply's, harddisks or cpu's but on duplicate servers. Also duplicating every component in the servers would only affect the pricing on those.

I would consider putting one of the servers NOT on UPS. Sometimes the UPS is the cause of the power failure

 

[gblucas]

As I understand it, Avaya believes that these servers are redundant, and having redundant power supplies, mirrored hard drives and such are NOT neccessary, because if something were to go wrong with one server, the other one would just take over until the first one could be repaired.

In the world of Microsoft and servers...You would make as many things in the server rundundant as you could, especially mission critical servers...

Don't you think that these are just as mission critical...

I know that I do, but some engineer somewhere must not think that...

This is my opinion as well as a couple of Avaya techs and BP techs that think the same thing...

The point is that the Network Admin's here want to buy the part from Buy.com and hot swap it in my servers - -when I'm not looking! I'm completely satisfied with the current solution. If anyone get's any other answers I'll be interested. Thanks!

gblucas,

Well maybe in the "Microsoft world" redundant servers don't work as designed and you would never want to rely on the backup servers ?

Of course those servers are mission critical but where do you draw the line in the end ? Putting 2 telephone sets on every desk ?
Better put in a duplicated ESS if you want a good backup solution.

Toni269,

The problem is your network admins are looking at a telephony solution they think is just another pair of windows servers running on HP machines.
Try to make them clear that it's another concept of redundancy and tell them they may turn one of your servers off and you're confident with that. Next tell them you're going to turn off one of their servers randomly and ask them how confident they are about that

 

[Toni269]

ROFL!!! I love it!

Actually I do have two phones at each desk, the digital and a backup Centrex. We are emergency response 24x7, (hypersensitive to outages/downtime). Always looking for Business Continuity solutions.

Thanks!

From looking around in here for a long time now, the failover doesn't always failover. I went through this not long ago and every set I had in 5 (large cabinets) reset.

With 5800 sets in a hospital environment (Level 1 trauma center and Level 1 Burn center), our administrators do not have a big since of humor around here on things that could be life threatening. Not being able to call the code team, overhead page, operators in the event of a disaster, or our main number could possibly result in just that. So I could see adding whatever needed to at the very least keep my redundancy and keeping this from ever going to a failover.

mikeydidit,

s8710 is just a hp dl380 generation 3 servers. you can call any hp shop out there and buy a power supplies for these, they're universal. they're hot swappable so you can plug one into standby server and see what happens. i think nothing will happen, except that you'll get redundant power supply in a server.
as for violating avaya maintenance, i don't think they will inspect your system on site. and if you don't tell 'em, they wouldn't know.

 

[mikeydidit]

That was kind of my thinking dwalin. I cant see where it would hurt to have redundant power supplies.

[Toni269]

Ok, then here's the plan... One of you do it first, lemme know how it goes then if nothing blows up then maybe I'll try!

 

[mikeydidit]

LOL, I was going to let you try it first.........

You still have my number, call me and let me know how it goes.

Hey Mikey, back in the days when you were doing those cereal commercials you always tried everything first so don't try to weasle your way out of this!
