The HPE 7.68TB SAS 12G Read Intensive SSD (P04523-B21) delivers 7.68 TB of capacity in a 2.5in SFF form factor, 12 Gb/s SAS interface, read-optimized performance, SmartCarrier (SC), digitally signed firmware and a 3-year warranty.
Read intensive classification means the drive is optimized for workloads with heavy read operations (up to 95% reads), delivering high sequential throughput and random read IOPS for applications like content delivery, boot, cache and analytics.
The P04523-B21 SSD supports a 12 Gb/s SAS interface, enabling up to 2 GB/s of sequential read throughput for data-center applications.
The SSD is a 2.5-inch Small Form Factor (SFF) drive compatible with standard SAS backplanes and hot-swap drive bays.
HPE SmartCarrier is the drive carrier that provides status LEDs, QR code identification and tool-less mounting for simplified installation and drive health monitoring.
This SSD includes a standard 3-year limited warranty backed by HPE global support.
Digitally signed firmware ensures that only authenticated, HPE-verified firmware can run on the drive, protecting against unauthorized code and improving platform security and stability.
The SSD delivers up to 2 GB/s sequential read, 250 MB/s sequential write, 185,000 random read IOPS and 24,000 random write IOPS under typical operating conditions.
It is rated for 0.7 Drive Writes Per Day (DWPD) over a 3-year period, equating to approximately 6,100 TB of total writes (TBW).
This SSD is validated for HPE ProLiant Gen8, Gen9 and Gen10 servers including DL360, DL380, ML350 and blade enclosures with SAS backplanes.
Yes. The 2.5in SAS drive is hot-pluggable in supported HPE drive bays for non-disruptive field replacement.
Insert the SSD in an empty SAS bay on the HPE SmartCarrier, slide it into the server backplane until it clicks, then verify presence via HPE Integrated Lights-Out or storage controller software.
With high random read IOPS and low latency, the drive accelerates read-heavy database queries, virtual machine boot times and caching layers for improved application responsiveness.
HPE Smart Storage Administrator, HPE Integrated Lights-Out (iLO) and the HPE Service Pack for ProLiant (SPP) provide firmware version reporting and update capabilities.
Firmware updates are available on the HPE Support Center website or via the HPE Service Pack for ProLiant, accessible through your HPE support contract.
