Deployed Hardware Classes
We have purchased and retired multiple classes of server hardware over the years in staggered timeframes. In the general case we'll always have multiple overlapping classes of hardware as various warranty and support periods expire. These are the currently-active hardware configuration classes:
| Label | CPU Type/Speed | Phys Cores | RAM | Storage |
|---|---|---|---|---|
| A | 2x Xeon E5-2680 0 @ 2.70GHz | 16 | 96 GB | 2x Seagate ST9250610NS 250GB HDD |
| B | 2x Xeon E5-2640 0 @ 2.50GHz | 12 | 96 GB | 2x Intel M320 600GB SSD |
| C | 2x Xeon E5-2680 0 @ 2.70GHz | 16 | 192 GB | 2x Intel S3700 400GB SSD |
