SuperMicro SATA DOM

    For those that have not seen this before but are following another discussion where this has been mentioned, SuperMicro's SATA DOM (disk on module) is a very small, internal SSD product for SuperMicro servers designed around being used as a boot drive for hypervisors instead of slower and more fragile SD or USB storage. This is a full, but very small, SATA SSD.

    From SM's site:

    The Supermicro SATA DOM (Disk on Module), the SuperDOM, is a small SATA3 (6Gb/s) flash memory module designed to be conveniently inserted into a serverboard SATA connector to provide high performance solid state storage capacity that simulates a hard disk drive (HDD). Supermicro SATA DOMs are extremely reliable without any moving parts like standard HDDs and are smaller in size and lighter in weight with greatly improved performance, latency and power consumption (~ 1W-2W per SATA DOM vs. 6W-7W for an HDD).

    The Supermicro SuperDOM operates up to 2x faster than other SATA DOM products in the industry. Due to its optimized design the Supermicro SuperDOM does not require a 5V power cable as do other SATA DOM products on the market, thus improving performance and reliability. However, it is still backward compatible with server boards requiring this 5V power cable. The Supermicro SuperDOM is available in 16GB, 32GB, and 64GB capacities and supports all Supermicro SuperServer® products and solutions.

    The Supermicro SuperDOM is designed for use as a boot drive, backup recovery device, license drive, OS installation device (replacing CD/DVD-ROMs), embedded system storage element (to be deployed into very harsh environments where mechanical hard disk drives would fail), or in a thin client due to its small size and power requirements. The Supermicro SuperDOM can be ordered as an integrated unit with all Supermicro SuperServer® systems to create additional customer value.

    • Performance Advantage: Up to 2x faster than competitive products
    • Optimized Design: Approximately 1 sq. in. in size, no power cable necessary*
    • Power Savings: Consumes only 1~2w per module vs. 6~7w on HDD
    • Available in 64GB, 32GB, and 16GB models
    • Supports ALL Supermicro Server Solutions

  • SuperMicro recommends against RAID on the SuperDOM / SATA DOM modules but fails to explain why:
