The Garage Datacenter Hardware Stack ...

So lets get down to it, what is the hardware stack we are using for the application ...

Servers

Application Servers

The servers used to house the application in a HA and Load Balanced environment are the Compaq Proliant ML350 servers. They make up the first half of the applcation cluster'd environment

The servers each have the following specifications:

2 x Compaq Proliant ML350's Running
- Dual 1.4 ghz CPU
- 2 Gig of Ram
- 6 x 18.2 SCSI disk

The second half of the of the application cluster are the Compaq Proliant ML370 servers. The specification of the servers are as follows:

2 x Compaq Proliant ML370's Running
- Dual Pentium III 1.4 ghz CPU
- 2 Gig of Ram
- 6 x 18.2 SCSI disk

(pretty much the same as theh ML350's)

Database Servers

The database servers are also going to be configured in a clustered environment. They will be running the mySQL clustering suite over 4 servers. The servers to be used have the following specification:

4 x Compaq Proliant 6400 Running:
- Quad Pentium III 700mhz Xeon
- 3 Gigz of Ram
- 4 x 36.4 Gig hard disk

Storage Servers

The storage servers are used to store various files and videos that are uploaded by the users. The servers used for this purpose have the following specification:

2 x Compaq Proliant ML570 Running
- Quad Pentium III 700mhz Xeon
- 2 Gigs of Ram
- 12 x 36.4 Gig hard disks

Batch Processing Cluster

There are various batch job that need to be run and various user executed processes that can contribute to the workload on the application servers. These processes have been identified and have been migrated to a seperate cluster so that any execution of these processes do no conflict with the operations of the application servers. This is to ensure that the user browsing experience is not hindered or degraded by any backend processing jobs. The following hardware has been used for these servers

10 x Dell GX270 optiplex Running
- Pentium IV 1.8ghz
- 768 megs of Ram
- 1 x 70 Gig hard disk

Racking and Storage

All of the equipment mentioned above along with the switches and networking equipment is housed within 2 x compaq 9000 racks (white in color).

Well there you have it .... the initial datacenter setup. The next post is the more interesting area of hardware, that being ... how we procured all this hardware at reasonable costs.
