Compatibility

Samsung enterprise PM-series SSDs work in ANY interface-compatible server / storage array. Native Samsung PN is typically priced below OEM-branded (Dell / HPE / Lenovo / Cisco) equivalent — same physical drive, no OEM tray + service-tag premium. May require generic carrier or no carrier (vSAN ready nodes).

• PM893 / PM897 (SATA SSD 2.5" SFF): Dell PowerEdge 13G+, HPE ProLiant Gen9+, Lenovo ThinkSystem SR Gen1+, Cisco UCS C/B-series, Supermicro SuperServer — any SATA-capable backplane
• PM1643 / PM1645 (SAS-3 12G SSD): with PERC/Smart Array/RAID HBA — same OEM chassis as SATA
• PM1733 / PM1735 (NVMe Gen4 U.2/U.3): PowerEdge 14G+/15G/16G NVMe backplane, ProLiant Gen10+ Smart Carrier-NVMe, ThinkSystem SR Gen2/V2/V3 NVMe-capable
• PM1743 (NVMe Gen5 U.3): PowerEdge 16G+ (R660/R760), ProLiant Gen11, ThinkSystem V3 — tri-mode backplane required
• vSAN Ready Nodes: Dell VxRail / HPE SimpliVity / Lenovo HX use Samsung PM-series for cache + capacity tiers

Use Cases

High-IOPS production workloads — OLTP databases (SQL Server / Oracle / PostgreSQL / DB2), virtualization datastores (vSAN / Storage Spaces Direct / VxRail / SimpliVity), boot devices, VDI hot-tier, write-intensive logging, container persistence layer, AI/ML training data sets. RI for read-heavy DBs / VDI gold images; MU for general VM datastores; WI for SQL transaction logs + write-cache tiers. Power-loss-protection (PLP) standard on PM-series for crash-consistency.
