The server layer consists of three PowerEdge R740xd servers. The PowerEdge R740xd server is a 2U rack server that supports up to:
The following table describes the PowerEdge R740xd configuration that we used for the solution deployment:
Component | Base | App Direct Mode | Memory mode |
Chassis | 2-CPU configuration up to 24 x 2.5" hard drives including a maximum of 12 NVMe drives | ||
Processor | 2 x Intel Xeon Platinum 8280L (28 cores) CPU @ 2.70 GHz | ||
Memory | DIMM: 24 x 64 GB @ 2933 MT/s | DIMM: 12 x 64 GB @ 2933 MT/s | DIMM: 12 x 32 GB @ 2933 MT/s |
N/A | Intel Optane: 12 x 256 GB @ 2666 MT/s | ||
rNDC | QLogic 41264 Dual Port 10GBE SFP+ and Dual Port 1 GbE BASE-T, rNDC | ||
Power supply | Dual, Hot Plug, Redundant Power Supply, 2000 W, C19/C20 Power Cord | ||
RAID controller | PERC H740P RAID Controller, 8 GB NV Cache, Adapter, Low Profile | ||
iDRAC | iDRAC9 Enterprise | ||
Physical disk | 2 x 1.2 TB 10K RPM SAS 12 Gbps Hard Drive 8 x 960 GB SSD SAS Mixed use 12 Gbps 4 x Intel PCI NVMe SSDs P4610 (3.2 TB) |
We also connected a separate client server to the same network infrastructure to drive the benchmarking load on our solution, as shown in the previous figure. Using the Windows operating system, we created three separate VMs that host the HammerDB benchmarking tool to stress-test the respective servers. The servers are configured with Base, App Direct, and Memory modes.
