have lower capacity than the highest capacity 7,200 RPM drives. 10K and 15K drives are labelled Mission Critical or Performance Optimized, while 7.2K are called Business Critical or Capacity Optimized. Since 7.2K drives spin slower they can have larger platters and space for more platters in an HDD case. That allows for higher capacity drives – 16TB, 18TB, … Random read/write task speeds are usually measured in IOPs (Input/Output operations per second) and for 15K drives can be up to 290.

Dell offers different enterprise SSDs with different endurance ratings so customers can design the right solution for their needs. Below are the different categories (swim lanes) of enterprise SSDs Dell offers: ● Write Intensive (WI): 50/50 read/write workloads with highest endurance. HPC, Database logging, and caching are example workloads. ● Mix Use (MU): 70/30 read/write workloads with medium endurance. E-mail/messaging, OLTP, and E-commerce are example workloads.
7 Expansion cards and expansion card risers NOTE: When an expansion card is not supported or missing, riser the iDRAC and Lifecycle Controller logs an event. This does not prevent your system from booting. However, if a F1/F2 pause occurs with an error message, see Troubleshooting expansion cards section in the Dell EMC PowerEdge Servers Troubleshooting Guide at www.dell.com/poweredgemanuals.
