vecna.org Hardware
mozek.vecna.org
mozek is a Hewlett-Packard NetServer LH Pro (purchased at the MIT flea in the summer of 2003). he is old, narrow-minded, asthmatic, slow, and cranky, but he is the closest to a server-grade machine we have. the combination of his HP NetRaid controller and six-slot SCA drive array enables him to offer the most reliable disk storage on our network. someday i'll buy the appropriate daughtercard on Ebay and make him a dual Pentium Pro 200. his newest addition was a two-port USB card, which connects him to a printer.
he runs CentOS 3, since 4 won't install from floppy and he won't boot from CD or from the network or from USB.
he provides the following services:
- dns (bind 9)
- http (apache 2)
- ftp (vsftpd)
- ssh (openssh)
- sql (mysql)
- ipp and lpd (cups)
- http proxy (squid, still needs work)
- ldap (openldap, still needs work)
joyeuse.vecna.org
joyeuse is a Hewlett-Packard desktop machine of some flavor. he also runs CentOS 3, since i haven't gotten around to doing the OS upgrade yet. he currently has a significant chunk of my music archived (and sometimes shares it out, but not well; this functionality will be taken over by the MusicServer, hopefully before the end of the year) and handles my BitTorrent downloads for me. he does partial duty as a Linux workstation when i need one (but hey, i'd rather work on a Mac, and so i generally do).
- UPDATE joyeuse is currently suffering from hard drive failure and is offline.
New Hardware Purchase plans
Ok, I've had enough of struggling along with a network held together with spit and baling wire. Here's a plan for a solid basement-datacenter solution:
heh, shit, this package covers everything except the network power switch and the larger disks, just about. i've opened negotiations.
Servers - $2,000
one (1) file server - $598
- 2U/4U older x86 box will do; it's going to sit on an iSCSI-based SAN and just serve up its RAIDed drives to the frontend nodes
- something like this Intel ISP2150 would do nicely - $169
- maybe this one? - $295
- hmm, this one looks even better... - $200
- better still! - $110
- add a dual Intel 100baseT NIC for SAN connectivity (upgrade to Gig E later?) - will be trunked to help with latency - $41
- I already have an IDE RAID controller to put in
- it'll need two 800MHz PIIIs (or less - it really shouldn't need tons of CPU) - $48x2
- half a gig RAM at least, i'd think - $44
- i already have two 250GB IDE drives; if i buy two more (or two 300GB drives, even better), i can HW-RAID the two new ones, put an LVM VG on that, copy data from the old drives onto the new VG, HW-RAID the old drives together, and then extend the VG onto the new RAID. then i can create LVs and export them via iSCSI to the frontends. - $104x2
- this system will also need a pair of dinky IDE drives to be a software mirrored OS volume. - $20x2
- it would be very nice to have a good tape drive for backups; i already have a DLT drive that might be functional
two (2) front-end nodes - $701x2
- ideally 1U newer x86 boxes; more CPU, more RAM, but only need small mirrored drives for OS - $57, $40x2
- something like this Intel SR1325TP-E would fit the bill nicely, or an older, cheaper 1U box - $548
- CentOS 4.2, RHCS/GFS
- two 100baseT NICs (one for SAN, one for production network) - $8x2
Networking
- an additional 100baseT switch that's modern enough to support channel bonding; shouldn't need to be more than 8 ports
- this one would do nicely - $80
- a Linksys WRT54G wireless router to replace the Airport Base Station as our gateway router
Power
- a small rackmount UPS (just to protect against power blips and spikes)
- a networked power switch for fencing done! Carl Quillen donated two WTI RPB+ serial-controlled power strips; if i use the file servers to drive them, they should work fine.
Infrastructure
- a small machine rack to store all this stuff
