Frequently Asked Questions

What is the difference between an MSA tray SSD and a ProLiant Smart Carrier SSD?

HPE MSA tray SSDs (like P19558-001) are designed specifically for HPE MSA storage array drive bays, using an MSA-specific tray form factor. ProLiant Smart Carrier SSDs are designed for HPE ProLiant server drive bays. The trays are not mechanically interchangeable — an MSA tray SSD cannot be installed in a ProLiant server bay without a carrier adapter, and vice versa. Always order the appropriate tray format for your target system.

Why is SAS preferred over SATA for HPE MSA storage arrays?

HPE MSA arrays use SAS as the primary drive interface because SAS provides dual-port redundancy — two independent data paths to each drive — enabling non-disruptive path failover and multipath I/O. This is critical in shared storage arrays serving multiple hosts simultaneously. SAS also provides higher sustained IOPS and bandwidth for multi-host workloads compared to single-port SATA drives.

Can Read Intensive SSDs be mixed with Mixed Use SSDs in the same HPE MSA array?

HPE MSA storage arrays generally support mixing drive types, but within a disk group (RAID set), all drives should be of the same type and capacity for optimal performance and warranty support. You can create separate disk groups using RI SSDs for read-heavy volumes and MU SSDs for write-intensive volumes within the same MSA array, allowing workload-optimized storage tiers on a single array platform.

The HPE P19558-001 delivers 3.84TB of SAS 12Gb/s Read Intensive SSD capacity in an MSA tray configuration — providing high-capacity read-optimized SAS SSD storage certified for HPE MSA storage arrays, enabling all-flash or hybrid MSA deployments for VDI, read-heavy databases, and analytics workloads requiring high read IOPS and 3.84TB per-slot capacity in HPE MSA environments.
