What do you do for a job ?
clustering FTW, 10 seconds to fail it over, then worry about the server rebooting!Seriously, however, I'm a 'Technical Analyst'. It involves infrastructure support, and migration/implementation projects.
Currently looking at putting in a few HP blades, although I'm nervous as I'm aware that they have a midplane redundancy issue (a lack of, to be precise) but at the same time the only other viable alternative is IBM blades - and I've never played with them!
Ah well, same fun again tomorrow at 5am... Gotta love our security manager. Rather than fix the fact that the firewalls may as well not be there, he'd rather have me 'harden' the server estate making it impossibly difficult to change anything later.
lol, ILO rules, the guys at work still use RDC and I laugh at them when they do a recurring ping to see when the server comes back up again, watching the boot FTW!Pulling wires out is so 90s, hopping on the ilo and pressing down the virtual power button ftw
mm blades, we had a few (not much by most peoples standards granted) come in the other day. About 70k worth of blades (4 full height, 1 half height) sat at the end of my desk and it looked like hardly anything there! Think there for all our VM ware stuff (another area dk loves )
they must be BL680/685's with 4 processors for that spec!ILO rocks, watching a server boot, or 'pressing the power button' while sat at home is great
As for the blades, we've got an enclosure on 2 of our sites, one hardly has anything in, the other is filling up nicely now Couldn't believe the latest ones were 15k a piece though, can't remember the specs now though
Our guy who is the VM/SAN man is leaving next month so hopefully I'll get more involved in that stuff.
lol, tell me about overspeccing, we have just implemented sharepoint, did we use 1 server, no, did we use 2 or 3, no we had to use 5!!!!
2 front end, 1 index and 2 backend sql clustered, about 20k's worth, for a f**king intranet!!!!!
Ive not touched a server (besides the Dell thing powered by a P3 Xeon in our classroom) and i can only think the ccna (and the ccnp, Voip, Mcsa and foundation degree in computer science if i stay for another 2 years) wont be anywhere near enough for a job, i cant program either.
So basically im only doing networking s**t, and besides configuring a few switches and routers to run some s**t protocols like eigrp and ospf, i dont really know s**t yet.
Christ, I wish the monkies who apply for our first line support jobs knew this "little".
We're a firewall support company, and the only people we generally get for our first line stuff are desktop support guys with little or no network knowledge. Most of them don't even know about 3 way handshakes
With blades, the best thing I saw was an HP blade server running VMWare ESX and V-motion. Replacing desktops with thin clients that RDP into vvirtual desktops. Watching a youtube playback on one of them as the admin guy moved the virtual machines between blades without dropping a frame.
Never got into the nitty gritty of them though, only had to config the network side of them. Interesting beasts though.
I'll toddle off to the corner now muttering "it's not the bloody firewall......"

As for HP blades, no redundancy issue on the chassis or the midplane, it has no active components to fail (excpet for a chip containing the serial number, but I think you can do without that )

Nope, the qualifications won't be worth s**te. IMO.
I've got GCSEs. And half an A-Level. Experience from the age of 11 FTW!
What Firewalls do you deal with?
thats the beauty of blades, 1 network connection for all the ilo's through the onbard administrator!But that would require something other than the shitty 3Cum 'stack' (1Gb fibre between all the switches, apparently that's 'stacking' in their book) to have sufficient ports to plug all our server's NICs into, let alone their iLOs.
I've bucked the trend lately, not only have I just set up a site with the server NICs teamed, I've also plugged the iLOs in. And get this - I also configured them!
*Bangs head on wall*
the power supply problem I know about form last year, they replaced all of ours within 2 days which was good, it would be a VERY rare case for the entire chassis to shut down though because of it, we have had a power supply blow up and that took out the pdu but as we were running 6 PSU's in n+n it didn't affect anything really and we just replaced the psu with a spare and flipped the trip switch on the pdu.Until you get to Exchange, yeah. But then we can't use storage blades for clustering and we'd quite like the entire lot to sit in one box. As it happens, there is a pair of clustered blades going in, attached to an MSA2024 (IIRC) because they don't want to connect it to the EVA, as they're technically for seperate sides of the business.
Actually the Midplane only has one DC power rail to each blade, which means that should either a blade or power supply go wrong in a particular manner, then the entire enclosure shuts down. HP have issued a not insignificant recall for all Blade chassis power supplies manufactured pre August last year IIRC, in an attempt to over-engineer the power supplies so as not to fail. Granted, at least they've done something about it, but it's still a redundancy issue nonetheless.
And HP blades have a known issue with running the FB-DIMMs waaaaaaay over temperature - but then you'd know that too, and that whilst HP should have done something about it as they know the thermal requirements and dynamics of their own FB-DIMMs, it's actually down to the nature of the memory which requires an insane amount of cooling on it's own.
So no, I disagree - HP blades are far from perfect, however having very little experience of IBM stuff (and not having anything other than HP in our server room) it makes me wary to use anything else, as yes, HP blades are pretty good... Just not perfect
We have a clustered exchange mailbox role, works a treat, the other node is used for the file server so nothing is wasted, very handy when you need to reboot one of the nodes.Until you get to Exchange, yeah.

Goes from one extreme to the other though, had a server today that kept throwing up high cpu usage alerts in MOM. Checked the server, and it was an old P3 lol.
You mean you don't know your network inside out?! :approve:
presume you didn't buy that lot from us?Right had a look in our enclosure today to see what the new stuff we bought actually was.
4 x BL680, each with 4 x 6 Core Xeons and onboard admin reporting 50gig in each. To be used for our ESX stuff.
Then as well as that just some BL460s and a storage blade.
Think we managed to swing the enclosure and some of the other stuff on the intranet budget
Will have to dig out the specs of stuff that's totally overkill for what it's used for.

Almost ended up with some dell blades on top as they has some offer on where you got the enclosure and 2 blades for £3.
what the hell, if thats the case then it wasn't configured correctly if you've had that happen, we used to have an exchange 2003 cluster and it took seconds, 30 max to fail over.Does work a treat, but it takes up to half an hour for all the services to pick up...

You get the chassis and an interconnect free if you half fill the chassis at the moment, and by buying 4x680's you half filled the chassis right there, and at 6k for the chassis and another couple of grand for he interconnect (depending on which one) thats a good rebate!

this might be a bit of a thread hijack but i'll ask anyway.
for those of you that have made careers out of IT with no quals, how have you made the step up from messing about with home /desktop PC's onto servers, networking and a domains. I am confindent on any desktop PC and most software but we have a pretty basic terminal services server and another server (domain controller, I think, I'm not even sure! where do I learn this kind of thing!!)at work and I'm not really sure what it can do.
it might be a case of you don't know what you don't know but I'd kind of like to utilise it to it's maximum capabilities and I obviously have to be careful as the company runs off the thing but how does one go about making that step up and learning on my own?
