Why this tier?
- Processor: 2 × Xeon 6728P — 48 cores in total (24 cores, 2.7 GHz, 210 W per processor). The largest model usable in this configuration has 86 cores and the rule of this tier asks for at least 15% of that.
- Memory: 16 modules of 64 GB = 1024 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 Hard disk drives of 1.2 TB = 4.8 TB raw; 2.4 TB usable with RAID 6 (standard RAID formula, no overhead).
- Controller: MR408i-o with 4 GB cache.
- Network: 1 adapter(s) — 2 ports and 20 Gb nominal capacity in total (fastest port 10 Gb).
- Power supply: 2 × 1500 W (power-supply redundancy).
Selection rule of this tier
- The chassis with the fewest drive bays that still fits the drives of this tier (LFF, 4 drives)
- 2 processor(s) — the lowest-power (lowest TDP) model that has at least this share of the cores of the largest catalog model (15%)
- Memory: about 32 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: Hard disk, 4 drives with a capacity at the 50th 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
