DU494 Dell Perc 5/e Dual Channel 8port PCI-express SAS Controller

DU494 Overview

The Dell DU494 Perc 5/e SAS controller is a dual-channel device, which means that it can support up to two SAS channels for increased data throughput. Each channel supports up to four SAS devices, giving a total of eight ports for connecting SAS drives. This makes it an ideal solution for systems that require a large number of drives, such as storage arrays and servers.
256MB Cache: The Dell Perc 5/e SAS controller comes with a 256MB cache, which is used to improve data transfer speeds and reduce latency. The cache stores frequently accessed data in memory, allowing the controller to retrieve it more quickly than if it had to access the data directly from the disk.
