Features of Dell DX481 Perc 6/i SAS RAID Controller
The Dell DX481 PERC 6/i SAS RAID Controller is a hardware component used in Dell PowerEdge servers to manage RAID arrays. Here's some information about this RAID controller:
RAID Support: The PERC 6/i (PowerEdge RAID Controller) is designed to support various RAID levels, including RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, and RAID 50. These RAID levels allow you to configure multiple hard drives into arrays to achieve data redundancy, improved performance, or a combination of both.
SAS Interface: The controller uses a SAS (Serial Attached SCSI) interface to connect to SAS and SATA (Serial ATA) hard drives. This enables high-speed data transfers and compatibility with a wide range of storage devices.
Cache Memory: The PERC 6/i typically comes with an integrated battery-backed cache memory module. The cache helps improve performance by temporarily buffering data during read and write operations. In case of power loss, the battery ensures that cached data can be written to disk to prevent data loss.
Compatibility: The Dell DX481 PERC 6/i RAID Controller is compatible with various Dell PowerEdge server models, including many 9th generation and some 10th generation servers. However, please note that the compatibility of specific server models may vary, so it's essential to verify compatibility with your server model before installation.
Management Software: Dell provides management software, usually called "Dell OpenManage Server Administrator" or "Dell OpenManage Storage Management," which allows users to configure and monitor RAID arrays, manage virtual disks, and monitor the health of connected hard drives.
Obsolescence: As of my last update in September 2021, the PERC 6/i is an older RAID controller model. Dell might have released newer generations of RAID controllers with enhanced features and performance. If you're considering using the PERC 6/i in a server setup, it's worth checking for any updated models or alternatives.
