The HPE ProLiant DL360 Gen9 server supports various types of drives, including:

1. Small Form Factor (SFF) SAS/SATA hard disk drives (HDDs):

   These are 2.5-inch drives that provide high-capacity storage options for the DL360 Gen9 server. They are available in various capacities and rotational speeds (e.g., 10K or 15K RPM) to suit different performance and storage requirements.

2. Small Form Factor (SFF) SAS/SATA solid-state drives (SSDs):

   These are 2.5-inch SSDs that offer faster data access speeds and improved overall performance compared to HDDs. They are available in different capacities and provide higher performance for applications that demand high IOPS (Input/Output Operations Per Second).

3. Large Form Factor (LFF) SAS/SATA hard disk drives (HDDs):

   These are 3.5-inch drives that offer higher storage capacities compared to SFF drives, making them suitable for applications that require large-scale storage.

4. Large Form Factor (LFF) SAS/SATA solid-state drives (SSDs):

   These are 3.5-inch SSDs that provide high-capacity storage with faster data access speeds compared to LFF HDDs, making them ideal for performance-sensitive applications.

5. SATA M.2 solid-state drives (SSDs):

   These are M.2 SSDs that use the SATA interface and are designed for use in M.2 slots on the motherboard of the DL360 Gen9 server. They offer high-speed data transfer and storage options in a compact form factor.

6. NVMe solid-state drives (SSDs):

   These are SSDs that use the NVMe (Non-Volatile Memory Express) interface and provide ultra-fast data transfer speeds and low latency for high-performance storage. They are available in various form factors, such as U.2 or PCIe, and can deliver exceptional storage performance for demanding workloads.

It's important to note that the specific drive options and compatibility may vary depending on the configuration and model of the HPE ProLiant DL360 Gen9 server, as well as any additional hardware components or storage controllers that may be installed.
