The HPE P09923-001 is an 800GB SAS SSD for storing data in compatible HPE server systems. HPE lists it as a spare part, so it can serve when maintaining or expanding storage configured for this drive type.
Its 2.5-inch SFF size fits server bays designed for compact drives. SAS connectivity suits storage architectures using Serial Attached SCSI.
The MU classification means mixed use, rather than a write-intensive or read-intensive variant. The drive also has an SC smart carrier and DS digitally signed firmware. Its capacity and mixed-use classification suit general server workloads, including application data, when a compatible HPE SAS SSD is needed.
