The HPE Smart Array E208e-p SR Gen10 Controller is a PCIe Gen3-based SAS/SATA RAID adapter delivering 12 Gb/s throughput per port, supporting RAID 0, 1, 10, 5 and JBOD for HPE ProLiant Gen10 servers.
Which HPE servers are compatible with the Smart Array E208e-p SR Gen10?
The controller is validated in HPE ProLiant Gen10 rack and tower servers, including DL, ML and MicroServer models with available PCIe Gen3 x8 slots.
How many drives can the E208e-p SR Gen10 controller manage?
It supports up to eight SAS or SATA drives per controller via two external four-port SFF-8643 connectors.
Which RAID levels does the Smart Array E208e-p SR Gen10 support?
It offers hardware RAID 0, 1, 10 and 5 for data protection, plus JBOD mode for simple pass-through drive access.
What interface and bandwidth does the Smart Array E208e-p SR Gen10 use?
The adapter uses a PCIe 3.0 x8 host interface, providing up to 64 Gb/s aggregate bandwidth and 12 Gb/s per SAS/SATA port.
Does the E208e-p SR Gen10 include onboard cache memory?
This model is a cacheless controller that leverages server system memory for cache functions, simplifying deployment and reducing maintenance.
Can I use the Smart Array E208e-p SR Gen10 as an HBA (pass-through) adapter?
Yes. Enabling JBOD mode allows direct host access to individual drives for software-defined storage or hypervisor use cases.
Does the controller support NVMe drives?
No. The E208e-p SR Gen10 is designed exclusively for SAS and SATA HDDs and SSDs at up to 12 Gb/s per port.
How do I install the HPE Smart Array E208e-p SR Gen10 Controller?
Power off the server, insert the controller into a free PCIe Gen3 x8 slot, secure the bracket, reconnect drive cables to the SFF-8643 ports, and power on.
How do I configure RAID on the E208e-p SR Gen10?
Use HPE Smart Storage Administrator (SSA) during boot or within the OS agent to create logical drives, assign RAID levels and initialize arrays.
How can I update the firmware for the Smart Array E208e-p SR Gen10?
