dual monitor nvidia board lowered in resolution on new 1.0.8178 tis a geforce 5700 from gainward. darn thing ran dual at 1600x1200 per monitor now its running in one of the monitors is running at a lower resolution than the other.

Po' Man's SAN
by Charles Steinkuehler 02 Feb '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I work for a fairly small company and am getting ready for our next round of server upgrades (every 5-6 years whether we need it or not!). I'd like to get some of the benefits of having a SAN (mainly one place to add/manage raid-cards & HDDs), but don't really need the performance or sticker-shock of the commercially available units. Basically a big chunk of SATA RAID storage I can share between a few systems (mail server and a couple of file servers) would be ideal. I'm currently thinking the ATA-over-Ethernet stuff looks like about the right fit...no expensive fiber-channel, no accelerated TCP/IP cards required for decent performance (the protocol is raw ethernet, no IP involved). I can start off with 'dedicated' storage areas for each machine (using 'conventional' ext3/jfs/etc filesystems) , and graduate to something like GFS in the future, if necessary. I'd start out running over GigE copper, possibly bonding a couple interfaces on the actual data server (or maybe even migrate to 10GigE) if required for performance. Has anyone setup anything like this, or played around with AoE? Am I missing some obvious solution to doing the same thing without using 'exotic' technology like AoE, iSCSI, or <insert buzzword of the day>? I know a bunch of you run linux on 'real' hardware, but my experience has been limited mainly to the 32-bit x86 world, and software RAID [1|5] + LVM is about as fancy as we get. Any comments/pearls of wisdom will be greatly appreciated! - -- Charles Steinkuehler charles(a)steinkuehler.net -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFD4naMLywbqEHdNFwRAonuAJ4sG7O7TqonCN+7O41HLDXy47JeCgCfYbcq ythyQKcWJAgzaGAHwADugY4= =qiR9 -----END PGP SIGNATURE-----
