HPE Smart Array P410i SAS RAID Controller
The HPE Smart Array P410i is a low-profile, half-height plug-in card that provides eight internal SAS ports through two SFF-8484 connectors. It connects to the host via a PCI Express 2.0 x8 interface and uses DDR2-800 memory for operation. This controller suits administrators adding hardware RAID to compatible HPE ProLiant servers.
PCI Express 2.0 x8 host interface limits throughput
The card operates on a PCI Express 2.0 x8 link, which caps the maximum data transfer rate at 600. The two internal SAS ports share this bandwidth, so aggregate throughput cannot exceed the host bus limit. Systems restricted to PCIe 1.x slots will reduce available bandwidth further.
RAID level support determines array options
Hardware RAID 0, 1, 1+0, 5 and 5+0 are supported natively on the controller. RAID 6 and 6+0 require the separate Smart Array Advanced Pack license key and a compatible cache upgrade. Environments needing RAID 6 without purchasing the licence should select a different controller.

Questions about this item
Should I choose the version with 256 MB cache or the one with the battery kit for BBWC?
The controller can be upgraded with a minimum 256 MB cache module and a battery kit for BBWC, so you can add either later.
What does the 600 MB/s maximum transfer rate mean when the card is installed in a server?
The 600 MB/s figure is the Serial ATA/600 interface ceiling; actual throughput depends on the drives and RAID level configured.
How does the PCI Express 2.0 x8 host interface limit the controller in practice?
The PCIe 2.0 x8 host interface caps the controller's bandwidth to the slot's maximum, which may restrict performance with heavy multi-drive workloads.
