| = 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. | == deleuze == * Location: Peer1 * Model: Dell PowerEdge 2850 * Processor: 2 x 2.8 GHz Intel Xeon * RAM: 4 GB * Disks: * 4 x 10K Seagate Cheetah SCSI drives, 73GB '''and''' * 2 x 10K Seagate Cheetah SCSI drives, 36GB * Extra: RAID kit, with battery, etc., 256 MB RAID cache, 2 power supplies * OS: Debian stable * User logins: no * Source: donation by Justin Leitgeb |

| === 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: |
* Model: Dell PowerEdge 1650 * Dual P3 1.4GHz * 2G RAM * 18GB SCSI HDD * Source: donation by NathanKennedy |
| Line 39: | Line 67: |
| * 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. |
'''Use: ''' |
| Line 46: | Line 69: |
| 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. :) | == Nortel Baystack 380 switch == |
| Line 48: | Line 71: |
| There may be other factors influencing different configuration choices between the servers. | * Location: Peer1 * Nortel Baystack 380 switch * Input current: 1.5A to 100 AC * Input voltage (rms): 100 to 240 VAC at 47 to 63 Hz * Power consumption: 150 W * Thermal rating: 1000 BTU/hr maximum |
| Line 50: | Line 78: |
| 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). | * Source: donation by ShaunEmpie |

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.

| Line 80: | Line 93: |
| ''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.'' | We have a standard KVM to allow remote switching between servers as maintenance requires. |

| ''Depends on their needs. If they want to run MRTG, then they need a managed switch. If they just need a switch, a netgear or linksys or d-link will accomplish the job. '' ''Cost differences are greater managed versus non-managed. Non-managed can be 50-$100, whereas managed can start at about $250 and go into the $thousands depending on model and capabilities.'' I also asked he.net about the number of ports we would need. Also got useful information about setting up a VLAN which would be useful. He.net response: ''(2 * n) + 1... where n is the number of machines you colocate. '' ''For 3 servers, your switch would need 7 ports. 3 for the private network, 3 for the public network, and 1 for the uplink to HE. '' ''For better control of your packets and their direction... if you're intending to do a public and private network, you might want to consider purchasing 2 smaller ElCheapoSwitches... or using a slightly more managed switch which support creating a VLAN.'' === Proposed Models and Vendors === ==== Vendors ==== [http://newegg.com/ Newegg] has been recommended to several of us. ==== Models ==== ===== NETGEAR GS108 10/100/1000Mbps ===== [http://www.newegg.com/Product/Product.asp?Item=N82E16833122111 Netgear GS108 Switch ]: Highly-rated Netgear switch that is not rack-mountable Price: ($56.99) MichaelOlson thinks that we should go with the Netgear switch. It has been rated as a very reliable product, and is very affordable. I don't like this switch for the following reasons: 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. 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 ===== Level One GSW-1655 10/100/1000Mbps ===== * ($249.99) Level One 16-port rack-mountable switch [[http://www.newegg.com/Product/Product.asp?Item=N82E16833118021 link ]] I've never heard of this brand (Level 1?) so I don't trust it. Any reviews? JustinLeitgeb ===== 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. ===== 3Com® SuperStack® 3 Switch 3812 ===== [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? ===== 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. I just work with nortel switches every day as an engineer. The 380 I can donate, as I own it. It is not brand new but is working. Here is a guide that I was able to find to give anyone interested a more in depth view of it, [http://vpit.net/es380-guide.pdf es380 guide]. Both are managed, 10/100/1000 switches. == 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.
