C6400 chassis options and drive enumerations C6400 chassis - 24 x 2.5-inch NVMe drive configuration The C6400 chassis with 24 x 2.5-inch NVMe drive configuration supports NVMe backplane and up to six NVMe drives per sled and a total of 24 NVMe drives per chassis. NOTE: ● The NVMe backplane supports only NVMe drives, It does not support SAS/SATA drives. ● The NVMe backplane is PCIe Gen4 capable and can support both Gen4 and Gen3 NVMe drives. It is not recommended to install all Gen3 drives on the NVMe backplane since each drive gets only x2 Gen4 lanes (compared to x4 Gen3 lanes in the existing NVMe backplane), which impact the drive read/write performance. ● For Gen3 drive installation, It is recommended to install up to eight NVMe drives for 24 x 2.5-inch NVMe backplane.

NOTE: ● The chassis is optimized for High-Performance Computing (HPC), High Performance Data Analytics (HPDA), Saas/IaaS, Financial Modeling, vSAN. ● Using an M.2 boot drive in each C6520 sled enables use of front 2.5-inch drives entirely for application data. ● An NVMe PCI card can be used in the LP slot in each C6520 to provide high performance storage for say writes/cache.

C6400 chassis options and drive enumerations
C6400 chassis - 24 x 2.5-inch NVMe drive configuration
The C6400 chassis with 24 x 2.5-inch NVMe drive configuration supports NVMe backplane and up to six NVMe drives per sled
and a total of 24 NVMe drives per chassis.
NOTE:
The NVMe backplane supports only NVMe drives, It does not support SAS/SATA drives.
The NVMe backplane is PCIe Gen4 capable and can support both Gen4 and Gen3 NVMe drives. It is not recommended
to install all Gen3 drives on the NVMe backplane since each drive gets only x2 Gen4 lanes (compared to x4 Gen3 lanes in
the existing NVMe backplane), which impact the drive read/write performance.
For Gen3 drive installation, It is recommended to install up to eight NVMe drives for 24 x 2.5-inch NVMe backplane.

C6400 chassis - 24 x 2.5-inch SAS/SATA drive configuration
The C6400 chassis with 24 x 2.5-inch SAS/SATA drive configuration supports SAS/SATA backplane and up to six SAS/SATA
drives per C6520 sled and a total of 24 SAS/SATA drives per chassis.
NOTE:
The chassis is optimized for High-Performance Computing (HPC), High Performance Data Analytics (HPDA), Saas/IaaS,

Using an M.2 boot drive in each C6520 sled enables use of front 2.5-inch drives entirely for application data.
