Questions & Answers
What is the HPE Smart Array P440ar/2GB FBWC 12Gb 2-ports Int FIO SAS Controller?
The HPE Smart Array P440ar is an integrated RAID controller featuring 2GB of flash-backed write cache (FBWC), two internal 12Gb/s SAS ports, and full I/O offload (FIO) acceleration for HPE ProLiant servers.
Which HPE servers are compatible with the P440ar controller?
The P440ar is compatible with HPE ProLiant Gen8 and Gen9 blade, rack, and tower servers that support mezzanine or FlexibleLOM expansion slots.
What RAID levels does the P440ar support?
The P440ar supports hardware RAID levels 0, 1, 5, 6, 10, 50, and 60 for flexible performance and data protection.
How much cache memory does the P440ar include?
The controller includes 2GB of flash-backed write cache (FBWC) to optimize write performance and protect data in case of power loss.
What interface and form factor does the P440ar use?
The P440ar uses a PCIe 3.0 mezzanine interface and installs directly into supported HPE ProLiant servers without occupying full-length slots.
Can I install the P440ar in a ProLiant blade server?
Yes, the P440ar is designed for HPE ProLiant blade servers with mezzanine slots as well as select rack and tower models.
Does the P440ar support SAS and SATA drives?
Yes, it supports both 12Gb/s SAS and SATA drives, enabling mixed-drive configurations for capacity and performance.
Can the P440ar controller be used with NVMe drives?
No, the P440ar is optimized for SAS and SATA drives and does not support NVMe media.
How does the flash-backed write cache (FBWC) enhance performance?
FBWC uses flash memory to preserve cached write data during power loss, improving write throughput and reducing rebuild times.
What throughput and IOPS improvements can I expect with the P440ar?
With two 12Gb/s SAS ports and 2GB FBWC, you can achieve up to 1.2M IOPS and multi-gigabyte per second throughput, depending on drive configuration.
