| During the HCoop IRC meeting on June 24, 2006, the group decided that it would based it's new system architecture on the following pieces of hardware: | This page collects information on the hardware that we have installed or plan to install as part of HCoop infrastructure. |
| Line 5: | Line 5: |
| * Two robust servers, one that doesn't allow normal user logins, and one that does. * One switch to form a LAN between these servers. * One serial port device, to facilitate remote access to our servers. |

| Also, it was mentioned that we should research hardware support contracts from any vendor that will be selling us equipment. | = Peer1 = |
| Line 11: | Line 9: |
| Additionally, group decided that the server that HCoop currently owns, Abulafia, will be brought to he.net for shell service. This will follow a necessary re-load of the OS software at a time to be determined later. | Current pictures of the actual Peer1 cabinet are at [[OnSiteVisits/20130627]]. |

| These servers should be as redundant as possible. At this point, we cannot afford to have less than one point of failure in many areas, so we should look for the following features in our new servers: | === KVM: navajos === |

| The admin-only server will hopefully be serving an AFS file system, which means that fancier kinds of RAID are justified there. The all-members server can get away with cheaper (and maybe even faster) solutions for local disk access. | Location:: virtual machine on fritz Allocated Resources:: 4 processors, 3G RAM, 30G storage Operating System:: Debian Wheezy AMD64 User Logins:: Yes Intended Use:: Member shell and server hosting Details:: ServerBog |

| JustinLeitgeb thinks that perhaps RAID 1 would work on the all-members server, and either RAID 5 or RAID 10 on the admin server. It should be RAID 10 if we can afford it, or RAID 5 if we're shorter on cash. :) | === KVM: mccarthy === |
