Along with Intel’s release of the fourth-generation Xeon Scalable processor in January this year, Dell’s modular infrastructure platform product line, the multi-node server PowerEdge C series, also launched a new generation model C6620.
Compared with the previous model C6520, the C6620 is also a 2U chassis that can accommodate four 2-way computing nodes. The most notable difference is the Intel Xeon Scalable processor generation, and the maximum number of CPU cores that the entire server can provide , each of which is 320 (40 x 2 x 4) and 448 (56 x 2 x 4); in terms of memory configuration, each computing node can be installed with 16 DRAMs, with a maximum capacity of 4 TB. The difference lies in the supported DDR4-3200, DDR5-4800; and in the part of PCIe expansion interface, C6520 provides 4 4.0 slots (3 x16, 1 x8), which can install 2 GPU acceleration cards with thermal design power consumption of 70 watts, C6620 provides Two 5.0 x16 slots, which can install a GPU accelerator card with thermal design power consumption of 70W.
It is worth noting that although the height of the chassis used by the two generations of products is the same as 2U, and many specifications are similar, there is a big difference from the comparison of the details.
For the C6520, the matching case is the C6400, which is the same as the previous generation C6420. In terms of hard disk configuration, both models of the C6400 case provide no backplane and are directly connected to 12 3.5-inch hard drives. As well as three configuration options including direct connection of 24 2.5-inch hard drives (if NVMe solid-state drives need to be equipped with 2 universal ports), the C6400 chassis used by the C6520 provides an additional backplane that supports 24 sets of NVMe solid-state drive configurations , As for the power supply, the C6400 chassis of the two models supports 1600 watts, 2000 watts, and 2400 watts. The C6400 chassis adopted by the C6520 supports an additional 2600 watts.
As for the latest C6620, the matching chassis style is C6600, the appearance depth is slightly reduced (from 570.34 mm to 549.7 mm), and the hard disk configuration has been greatly adjusted: it can be equipped with 16 2.5-inch SATA, SAS or NVMe Interface traditional hard disk or solid state hard disk, or with 8 sets of NVMe solid state hard disk in the shape of E3.S, instead of providing 3.5-inch hard disk matching options; the power supply part can be matched with 1800 watts, 2400 watts, 2800W, 3200W components.
Perhaps in response to the latest generation of server processors from Intel and AMD, they began to provide CPU models with higher thermal design power consumption than before. It is necessary to help IT managers grasp the operating status of the server chassis and improve the overall cooling efficiency of the server system. Apparently Dell also introduced some special designs on the C6600 that are different from the past.
For example, in addition to the adjustment of the specifications supported by the hard disk storage backplane, the C6600 chassis also adds multiple system boards with different dedicated functions, such as the chassis management board (Chassis Management Board, CM Board), power distribution board (Power Distribution Board) , PD Board), control panel combined with LED display/LED board (ear board), midplane board (Midplane board), thermal sensor board (Thermal sensor board).
As for the cooling fan, in order to cope with the fact that the C6600 itself supports three storage configurations including no hard disk (Diskless), 8 E3.S solid-state drives, and 24 2.5-inch hard drives, Dell also provides different configuration methods here. . If the first two configurations are used, multiple 80mm fans can be installed on the front edge of the server case.
If it is the last configuration, not only can multiple 80mm fans be installed on the front edge of the server case, but also two 60mm fans can be installed on the left and right sides after that, and one 40mm fan can be installed in the middle of the case. millimeter fan.
