(Redirected from Traffic cache hardware)This is an overview of our currently deployed and active cache hardware at the Traffic layer.
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 | Model | CPU Type/Speed | Phys Cores | RAM | Cache storage | NIC speed, type, driver | DC Ops Config |
|---|---|---|---|---|---|---|---|
| F2 | Dell R440 | 2x Xeon Gold 5118 @ 2.3Ghz | 24 | 384 GB | 1x Samsung PM1725b 1.6TB NVMe (HHHL Card) | 10G, BCM57412, bnxt | F-10G, +storage card |
| F3 | Dell R440 | 2x Xeon Gold 5118 @ 2.3Ghz | 24 | 384 GB | 1x Samsung PM1725b 1.6TB NVMe (HHHL Card) | 10/25G, BCM57412, bnxt | F-10G, +storage card, +10/25G NIC variant |
