HP BL460 Blade Servers G7 vs G8 vs G9 Evaluation

HP has a solid chassis lineup for their blade servers, but if you don't purchase 100 blades all at once, you may be stuck with various Generations "G"s of their blades.

G7 - the LOM was fixed based on the base part number you started with. Then you add mezzanine cards of various models. The SD Chip to boot, is right on the side of the blade.

G8 - So, now you can CHOOSe the LOM module you want and swap it out if you want. You can add mezzanine cards, but WOW, the G7s don't fit in the G8s. A big disappointment to me when I had 8 extra 10GbE FlexFabric adapters from the G7s at 3K each and couldn't put them in the new G8s.

NetApp E-Series

I'm going to get an E5660 to play with soon. I want to see what it will be like as a target for backup. Looks like a pretty good bulk storage unit, 10GbE interface with iSCSI, or if you want, you can do 16Gbit FC. I'm going to stick with the 10GbE, because I have a lot of ports on the Cisco Nexus 5596s and the HP Blade chassis is connected to that as well.

HP has their 3Par 4200 series, but it was a lot more expensive than the E-Series.

Waiting on the stuff to come in, then I'll post more.

Linux Virtualization

OK, so they tell me I need to make a bunch of Linux desktops availbel to some people that want to get access to some Linux desktops and then actually use them. SOOOoooo.

I venture into Linux VDI. is my final resting place for this. The add-on packages run on a RedHat Enterprise virtualization host, and it looks like Fedora or CentOS will work as well. So I'm going to try all of these and see what works the best.

First I'll get RHEV-M running on a machine and go from there. Spice looks like it needs it's own server, I'll make that a VM on this host.

Hardware. I've got an old HP DL380-G6 hanging around with 72GB RAM, should do nicely. Need to find some HDs. I'll start with just some 300GB SAS Drives, but we will eventually try swapping that out with a 3 drive array of SSD drives to see what that does for our performance.

More to come, stay tuned. Comment if you're watching, so I know to update more often.
