HAving testing the nibmle
they have good support, however there were two problems for me:
1) at the time it was iscisi only
2) If you are have parallel streaming reads, and try and write, performance collapses like a sack of shite (9/1 read to write ratio, 1gig ethernet, to a 10gig switch.)
However I can see that its grand for VDI and the like. However for us it wasn't a good fit.
But is the vSAN any good? is it fast, is it cheaper than alternative block storage?
or even a NFS share exported from GPFS/ZFS/StoreNext/*
If you're using HP workstations its proberbly cheaper to use the dl380s than a beefy z820.
I know you can get at least one k5000 into the dl380, I can't see why you wont be able to get two. Super micro can defiantly do it.
As for "servers aren't optimised for graphics" that's patently bollocks. What do you think most workstations are? server motherboards in a fancy box.
Gah, I just want stats
I've just bought a new storage system, and the hardest part is cutting through the sheer magnitude of bullshit.
For example; my requirements are fairly simple: 14000 iops peak for 10 ESX host via FC and 1gigabyte a second bursting stream 75% read 25% write. around 100TB of total storage.
Firstly I don't take too well to salesmen telling me that I can replace my currently array (75*15k sas) with 2 100gig SSDs in raid 1 and 12 10k SAS drives. "we've modelled your dataset" You've done fuck all sonney jim, you don't even know what we are doing in ESX. I take even less well when I specifically tell them I'm not going to by their rack, and they quote me for it anyway.
After testing 6 different suppliers we gave up on the unified block/filer and went balls deep into GPFS/v7000 combo.
They might be, but only if they stop randomly changing stuff every 5 minutes.
Seriously, trying to support a google apps domain, in anything other than a small company is a massive arse wedge. we use google hangouts to run meetings, in the space of three months, the layout changed no less than 5 times.
Did we get a warning? did we fuck. I can understand that if I was a freetard then yes, we'll just have to shut up and swallow google's milky goodness. But we're not, we pay for the privilege and get fuck all support.
As soon as I have time I'm migrating us the hell away from google.
EMC may have good kit
But they are expensive and the sales team don't listen.
I'm currently in the middle of a "storage off" 6 vendors, only one will succeed. EMC failed at the first hurdle.
The brief is/was clear: 150TBs of unified storage, 1tb or there abouts of flash, 15tbs of 15k (currently we have 75 spindles of 15k) the rest NL-SAS. NFS/CIFS at 10gigs block on 8gig FC
What was the spec they recommended? 3x100gig ssd and 15x600tb 15k drives. The rest of the space with ~40 spindles of 3tb NL-SAS.
The cost? ~£300k
plus I have to buy their stupid branded rack, even after I expressly told them no.
When I quizzed them they effectively shrugged
He is/was the only person I've met to have a scanning electron microscope *and* missiles in his garage.
Its not that powerful, however its fairly immune to network based attacks:
Your dad rocks.
Local heroes == *awesome*
I was looking at the midrange "converged" offerings from HP, and they really aren't that compelling.
Don't get me wrong, if you want a fast lump of block storage thats solid and reliable, the HP all the way. (we have two fully loaded p2000s) However, if you want to do file exports then it, on the face of it all falls apart. You have the choice of the "storevirtual" stuff, which when we looked at it at the beginning of this year looked pretty weak.(especially compared to netapp fas32** and VNX5***)
If I was going to risk things then I'd plump for a nextenta or similar. ZFS is starting to look really strong. Once the AD integration is sorted then It'll be a killer app. (I'm planning on using it for our nearline to see how good it is.)
The other issue is HP software, if they seriously want me to buy software(or "appliances") from them they need to actually *test* it first. The prime example is dataprotector. It would choke on a million files. Bare in mind it was shipped with a 48 tape LTO5 library, you'd have though it would have been able to handle such things.
If I was HP, I'd be thinking about a strategic linkup with nexenta to flog pre-configured d6000 or the like. It'd be nice to get software support from people who actually appear to *test* and proper hardware support that HP normally delivers.
Re: Where it is?
Top tip for correct pronunciations is to avoid the west country oooaarrrrrrr
for example westcountry norwich == narrrRrrrisch
norfolk == Nar ich with a short sharp r
another example is roof. Westcountry == RooooOoooooooof
norfolk its closer to ruff as in dog noise. like woofter and change the w for a short sharp r (and no ter)
Also I've been here, as a kid. whilst it was still active (they'd moved out of the control room about 5 years earlier) The amount of power it used was/is mind boggling something like 10Megawatts
I know its not fashionable
But I'd rather pay the £120 a year for reasonable TV and radio with no adverts, that £25(minimum) a month to get millions of channels of repeats, imports and cheap knockoffs.
Choice is rendered pointless if you only have the choice of crap, more crap and repeats.
I spend a lot of time in the US, and frankly TV there is abysmal. The actual quality of the picture is utter rubbish, the amount of advertising is ridiculous. Four advert breaks for a 22 minute cartoon, really? No wonder why things like mythbusters have so many plot recaps in them.
Yes there is choice, but its the lowest common denominator. The discovery channel for example has descended into a reality TV channel, following fishermen, moonshiners, bike "builders" and people that buy stuff from other people. The best part is, they actually charge people to watch that crap.
Having said that, the BBC are not perfect. However BBC not perfect is far superior to American "premium" tv
I made a project with the Pi
Its measures how often the shard is in cloud. From that you can then work out how much cash the
bourgeoisie* have lost through rubbish views.
