High Scalability – High Scalability – A Yes for a NoSQL Taxonomy.

There’s so many “not mysql” options out there that I don’t understand the subtle differences between.  This helps a lot.

How to backup an A10 Networks AX Series Load Balancer

Tuesday, November 10th, 2009

AX#conf
AX(config)#backup config tftp://<yourserver>/a10_backup.tar.gz
System files backup succeeded
AX(config)#

Notice you want to supply the .tar.gz suffix yourself.

Then on the receiving server server there’s a slight trick to unpacking it: its actually a tarball *within* a tarball thats then gzipped. It also doesn’t create a subdirectory for itself so it’ll explode all over the dir you’re in when you type the tar command.

RHEV to require a Win2k3 management server

Monday, November 9th, 2009

via Red Hat Virtualization Manager for Windows Only? – InternetNews.com.

tl;dr – qumranet built it using WPF, redhat’s re-writing it but wanted to get RHEV out the door before thats done.

I’ve seen redhat’s closed-source aquisitions go fairly terribly (gfs/clustersuite, netscape directory server) so I gotta admit I have low hopes for this.

On the plus side, the comments learned me about “proxmox-ve”, gonna look at that more later.
