Re: Personal Co-location Registry
many servers are also starting to feature IPMI <nanog@merit.edu> which allows for the remote console (that provides the VGA output slow.. only good for emergencies or for Windows servers) and power cycling of servers. Compaq/HP includes this feature in their Proliant servers, and many other white box vendors do too via the re-selling/integration of machines/motherboards from companies like SuperMicro.com. if anyone has some really specific questions about IPMI and various motherboard manufactures i might be able to help out as i work as a Sr. System Engineer at a white box company (but in reality i'm a unix hack/administrator) -mike -- hanulec@hanulec.com cell: 858.518.2647 && 516.410.4478 https://secure.hanulec.com EFnet irc && aol im: hanulec

if somebody posts a summary of command/control options for remote colo boxes i'd love to include it, or a pointer to it, at www.vix.com/personalcolo. i like the pc-weasel but i admit that my main system has a motherboard that's incompatible with it so i'm ready to consider an ethernet-based alternative. (i also have a number of 1U's that didn't have a free slot for a pc-weasel.) two thirds of the motherboards which advertise "serial bios" as an option don't produce any output. and some of them appear to use the com1 or com2 port in some kind of non-ascii mode which requires special software. i'm happy to add to the registry a list of things like pc-weasel and rtty and rocketport, but i'd like to have some confidence that it's a comprehensive list, which means that someone more familiary with the field has to build it. -- Paul Vixie

If someone is doing this, especially wrt to 1U servers, perhaps someone could provide a pointer to a reboot solution that would allow a single reboot device to control 42+ 1Us in a single rack. From my occasional interest in this area, I've seen lots of reboot solutions. Most of them take as many as 4-10 U to reboot 40 machines, which sort of obviates the need to reboot 40 machines in a single rack in the first place. Unless you use 10ft racks, I guess.

You could use dual vertical PDU's with serial management connected to a 1u serial console / KVM solution. There are a few vendors working on PDU's with IP / SNMP based management solutions but I don't think they have been introduced into the marketplace. Something like this could work: http://www.servertech.com/prod/remote%20power/rpm_ptxl_index.html It looks like the vertical version has a daughter mod that will allow remote management. Maximum of 32 AC interfaces per cab. /micah ----- Original Message ----- From: "Deepak Jain" <deepak@ai.net> To: "Paul Vixie" <vixie@vix.com> Cc: <nanog@merit.edu> Sent: Saturday, March 20, 2004 3:42 PM Subject: Re: Personal Co-location Registry

32 AC interfaces sounds like a pretty bad idea for the common 20A feeds available at most colos, and not smart for 40 1U servers even with 30A feeds. I find the BayTech RPC27 to be a reasonable solution, using 2x for a rack full of 1U's. If you get custom length power cables made, and interspace power connections from multiple servers, the logistics can be decent too. It's unfortunate that BayTech's pinout for serial console stuff is only slightly less evil than satan, but their power systems are nice. -- Richard A Steenbergen <ras@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)

You could do this with a combination of two vertically mounted BayTech RPC27[1] units per rack, and one Cisco 3640 w/ 3 * NM-32A and 1 * NM-1E2W's (and the appropriate octal -> RJ45 serial cables and DCE headshells) split between two racks. This would provide you with effectively 44 serial console ports (not counting the 2 per rack burned on the BayTech units) and 42 remotely controllable outlets at a space penalty of only 1U per rack. I'm doing something similar right now... -a [1] <http://www.baytechdcd.com/cgi-private/prodlist?show=RPC27>
