Hardware

1. New System Hardware

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:

Also, it was mentioned that we should research hardware support contracts from any vendor that will be selling us equipment.

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.

This page will serve as a forum for collaborative research on the pieces of hardware that we need.

1.1. Servers

We will be purchasing two servers, which will be configured and sent to he.net for colocation.

1.1.1. Desired Features

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:

1.1.1.1. Differences Between the Servers

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.

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. :)

There may be other factors influencing different configuration choices between the servers.

1.1.2. Proposed Models and Vendors

Vendors:

Models:

Note that when I checked Dell dropped something like $1200 off of the price of each server over $4000, so we should expect some significant discounts. Whichever company we plan on going with, we may be able to negotiate lower prices by emphasizing that we may buy more in the future, etc.

1.2. Ethernet Switch

1.2.1. Desired Features

1.2.2. Proposed Models and Vendors

[http://newegg.com/ Newegg] has been recommended to several of us.

MichaelOlson thinks that we should go with the Netgear switch. It has been rated as a very reliable product, and is very affordable.

1.3. Serial Port

Docelic, or other users -- please update this section since I am entirely ignorant about these devices! :)

1.3.1. Desired Features

1.3.2. Proposed Models and Vendors

[http://www.cyclades.com/ Cyclades] was mentioned as one vendor of serial port devices which are linux-friendly.
