Frequently Asked Questions

What is the difference between P36999-B21 and P37065-001?

Both are HPE 1.92TB SAS 12Gb/s Read Intensive Digitally Signed SSDs with Smart Carrier for Gen8/G9/G10 — functionally identical. P36999-B21 is the standard HPE option kit (-B21) for channel/reseller ordering, while P37065-001 is the HPE factory/OEM (-001) variant. Both are fully interchangeable in supported HPE Gen8, Gen9, and Gen10 servers.

What is the advantage of SAS over SATA for 1.92TB SSD in HPE servers?

SAS 12Gb/s provides dual-port redundancy (two independent data paths per drive), enabling non-disruptive path failover in multi-path SAS configurations. SAS also supports longer cable runs and higher sustained IOPS under heavy I/O queue depth versus SATA. For enterprise servers with redundant SAS controllers and multipath I/O, SAS SSDs provide higher availability and sustained performance compared to single-port SATA SSDs.

Is 1.92TB the maximum capacity available for SAS Read Intensive SSD in Gen8-Gen10 servers?

No — HPE offers larger SAS 12Gb/s Read Intensive SSDs including 3.84TB (P18428-B21 for SATA, K2P91B for SAS/3PAR) for Gen8-Gen10 compatible platforms. For Gen10 Plus and Gen11 servers, SAS 24Gb/s SSDs and NVMe U.3 SSDs provide higher capacity options. Verify the maximum SSD capacity your specific HPE server model and Smart Array controller supports via HPE QuickSpecs.

The HPE P36999-B21 delivers 1.92TB of SAS 12Gb/s Read Intensive SSD capacity with Smart Carrier and Digitally Signed Firmware — providing broad-generation HPE compatibility across Gen8, Gen9, and Gen10 platforms for read-intensive enterprise workloads requiring dual-port SAS reliability, 400,000 random read IOPS, and 1.92TB per-slot SSD capacity in 2.5-inch SFF hot-swap configurations.
