Dell 13th and 14th Generation PERC Cards
The Dell PERC (PowerEdge RAID Controller) H730, H730P, and H740P are RAID controllers that provide high-performance and reliability for Dell PowerEdge servers. Here are the main differences between them:
H730: The H730 is a RAID controller that supports up to 16 internal SAS or SATA hard drives or solid-state drives (SSDs). It has 1GB non-volatile cache memory and supports RAID levels 0, 1, 10, 5, 50, 6, and 60.
H730P: The H730P is an enhanced version of the H730 with added features for higher performance and reliability. It has 2GB non-volatile cache memory and supports RAID levels 0, 1, 10, 5, 50, 6, 60, and 00.
H740P: The H740P is the latest RAID controller in the series and provides even higher performance and reliability. It has 8GB non-volatile cache memory and supports RAID levels 0, 1, 10, 5, 50, 6, 60, and 00. It also supports NVMe drives and can be used in conjunction with Dell EMC's OpenManage storage management software.
Overall, the main differences between these RAID controllers are the cache memory, RAID level support, and added features such as NVMe drive support. The H740P is the latest and most advanced controller, but the H730 and H730P can still provide reliable performance for many business applications.
