Why this tier?
- Processor: 2 × Xeon E7-8893v2 — 12 cores in total (6 cores, 3.4 GHz, 155 W per processor). The largest model usable in this configuration has 15 cores and the rule of this tier asks for at least 25% of that.
- Memory: 16 modules of 16 GB = 256 GB. This platform has 8 memory channels per processor; 8 modules per processor means 1 module(s) per channel and all channels are filled equally (the QuickSpecs memory-balance recommendation).
- Storage: 4 SSD drives of 0.48 TB (endurance MU) = 1.92 TB raw; 0.96 TB usable with RAID 10 (standard RAID formula, no overhead).
- Controller: P430 with 2 GB cache.
- Network: 1 adapter(s) — 2 ports and 20 Gb nominal capacity in total (fastest port 10 Gb).
- Power supply: 2 × 1200 W (power-supply redundancy).
Selection rule of this tier
- The chassis with the fewest drive bays that still fits the drives of this tier (SFF, 4 drives)
- 2 processor(s) — the highest-frequency model that has at least this share of the cores of the largest catalog model (25%)
- Memory: about 128 GB per processor; number of modules = memory channels (8 channels per processor) × number of processors, one module per channel (two when needed) so that the channels are filled evenly
- Storage: SSD, endurance MU, 4 drives with a capacity at the 40th percentile of the available capacity list
- RAID controller with the least cache
- Network: an adapter with a total capacity close to 20 Gb
- Power supply: the smallest AC model with at least 1 times the estimated peak consumption (processor TDP + GPU + 200 W), two identical supplies
