PCIe 4.0 x8 RAID controller for dense storage arrays

The Broadcom 05-50076-00 MegaRAID 9580-8i8e is a new PCIe 4.0 x8 RAID controller designed for rack-mounted servers. It supports RAID 0, 1, 5, 6, 10, 50 and 60 plus JBOD mode for software-defined storage. The low-profile form factor with side-mounted SAS connectors enables a form-factor friendly cable exit. CacheVault flash cache protection helps preserve data during power loss.

Ideal for high-device-count SAS and SATA deployments

This card suits administrators who need to connect up to 240 SAS or SATA devices per controller in a single slot. It also supports up to 32 NVMe devices for mixed workloads. Builders requiring internal-only port layouts or full-height brackets should evaluate other options. The feature set targets critical, high-bandwidth applications rather than entry-level arrays.

Maximum device count per controller

The decisive specification is the ability to address 240 SAS/SATA devices or 32 NVMe devices from one controller. This density determines whether the 9580-8i8e matches the scale of the planned storage topology. Lower device-count requirements may be met by simpler adapters.

Questions about this item

How do I install the MegaRAID 9580-8i8e in a rack server with side-mounted SAS connectors?

Insert the low-profile card into a PCIe 4.0 x8 slot, then route cables through the form-factor friendly side exits to avoid blocking adjacent slots.

What maintenance will the CacheVault flash cache protection need over time?

The CacheVault module uses a supercapacitor instead of a battery, so no scheduled replacement is required.

At what device count does the controller hit its limit when connecting NVMe drives?

The controller supports up to 32 NVMe devices per card before reaching its maximum.
