= 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:		 #pragma section-numbers off
Line 4: Line 3:
 * 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.		 This page collects information on the hardware that we have installed or plan to install as part of HCoop infrastructure.
Line 8: Line 5:
Also, it was mentioned that we should research hardware support contracts from any vendor that will be selling us equipment. <<TableOfContents>>
Line 10: Line 7:
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. = Peer1 =
Line 12: Line 9:
This page will serve as a forum for collaborative research on the pieces of hardware that we need. Current pictures of the actual Peer1 cabinet are at [[http://hcoop.net/~rkd/hcoop/imgs/]], taken during [[http://wiki.hcoop.net/OnSiteVisits/20090821]].

=== 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:		 '''Use: email server, backup server'''
Line 39: Line 74:
 * Redundant power supplies.
  * How important is this really? -- ClintonEbadi
 * Hardware RAID.
 * Dual CPU's, AMD seems to be a stronger option than Intel
==== 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.		 == mire ==
Line 46: Line 76:
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. :) {{{#!wiki note

Perhaps we can get away with SATA RAID 1 on the web server -- hopefully this machine won't be IO-bound, especially if we add enough RAM later. Also, it might benefit us to get a couple of rather lightweight web servers behind a load balancer before really maxing them out, in order to have fewer single points of failure (of course, at this point we would probably also want to have two load-balancers using "heartbeats" so that they couldn't cause a prolonged system failure).  * [[RebootingMireSp]]

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.		 == kvm ==

With the Penguin models, we seem to have to go to the 2U, Altus 2200 in order to get a redundant power supply.		 The StarTech Server Remote Control External KVM over IP provides access to systems that may have a degraded network. It allows us to monitor Power-On Self Test (POST), configure BIOS/CMOS, and even reinstall operating system software. It must be connected to another multiple port KVM in order to have access to more than one server.

== Ethernet Switch ==
=== Desired Features ===
 * Gigabit
 * 5 ports minimum
 * Managed - so that we can troubleshoot failed NIC's easier
 * Rack-mountable, so that vibration and heat issues are diminished.
 * SNMP monitoring capability
=== Additional Information ===
He.net sent us the following when asked about switch configurations at their site:
Line 80: Line 121:
''We've got customers using everything from ElCheapoSwitch(tm) to Cisco-grade equipment. The main difference between the two is how much traffic they can deal with, the number of packets they can deal with, and how they can be accesses/monitored. If you're looking at pushing primarily web traffic (<50Mb/s) and do not require any of the more advanced functionality of a managed switch, you could likely just go with a good unmanaged switch. If you were doing higher traffic levels, streaming, or other such traffic which consist of a zillion little packets, especially if it's between your servers, you would be better served by something a bit higher grade.'' == hopper ==

Line 108: Line 170:
I don't like this switch for the following reasons:
Line 110: Line 171:
 1. It is not rack-mountable, meaning that it could raise issues for cooling in the rack, and be more susceptible to shock that could reduce reliability of the switch, or jar patch cables out of the ports. = Awaiting setup =
Line 112: Line 173:
 1. It is not managed, so we can't track important information about performance and possible NIC failures via SNMP.
Basically, I think that if we're going to pay all of this money for equipment and hosting, we shouldn't put an interconnect with insufficient features in the middle of our architecture. But, I'm not a networking expert, so I would welcome any opinions contrary to this! JustinLeitgeb		 None.

===== Dell PowerConnect 2716 =====
This is an 8-port gig switch that is web-manageable and lists for $82. I think that we could make it work, especially if I were able to write some scripts to get important data for monitoring in Nagios or rrdtool. I put the [http://www.hcoop.net/~leitgebj/hcoop_servers/pwcnt_27xx_specs.pdf specification sheet] on our web site. This switch is rack-mountable.		 We need a new KVM host and drives for staging offsite backups of openafs. See NewServerDiscussion2013

[http://www.3com.com/products/en_US/detail.jsp?tab=features&pathtype=purchase&sku=3C17401 3Com® SuperStack® 3 Switch 3812] seems to have most of the features that we need, with a bit of room to grow. Prices range from $1000 to $1500 on [http://froogle.google.com Froogle], in my experience [http://www.cdw.com CDW] is a reliable vendor. Perhaps we should make a jump and get the 24 port, which would support our use of an entire rack in the future, if the price difference is small?
Line 125: Line 180:
===== Nortel Ethernet Routing Switch 3510-24T and Ethernet Switch 380-24T =====
The 3510 will be much more robust than the others listed. List price is around $2200 but I will see how much of a discount I can get as wholesale is much much lower. Here is the product brief,[http://vpit.net/ers3510-brief.pdf ers3510 brief]. I can answer any questions about it as I do work for Nortel. I am not trying to make a sale here, as I am not a salesman.

== Serial Port ==
=== Desired Features ===
Is this device really necessary? For an extra $1000 - $2000, and utilization of 1U, I am not convinced that this is worth the expense. It seems that in the rare event that our machine is inaccessible from ssh we can use remote hands with he.net and put our resources elsewhere. If someone does think that this is necessary, please put a link to specific models that would be helpful, and a list of reasons why they will come in handy that would justify the additional cost and space in our rack.
