24-bay all-flash rackmount NAS

The Synology FS3600 is a 24-bay rackmount enclosure built for ultra-high performance with large user counts. It ships diskless and accepts 2.5-inch SAS or SATA solid-state drives. A 12-core Intel Xeon D-1567 processor runs at 2.1 GHz with turbo up to 2.7 GHz. Sixteen gigabytes of DDR4-2666 ECC RDIMM are installed.

Suited for I/O-heavy workloads.

This system targets databases, virtual machines and online transaction processing that demand over 193,000 iSCSI 4K random write IOPS. Four 1GbE and two 10GbE RJ-45 ports plus a PCIe 8-lane slot provide high-throughput connectivity. Organisations needing maximum raw terabytes per pound should look elsewhere.

92.16 TB ceiling with 128 GB memory headroom

Twenty-four bays support up to 92.16 TB of flash storage when fully populated. Memory scales from the factory 16 GB to 128 GB across four DDR4 slots for larger working sets. Power draw reaches 258.23 W under access and drops to 127.99 W in drive hibernation. Operating range spans 0 °C to 35 °C.

Questions about this item

Which drive types and how many bays does the FS3600 accept so my existing 2.5-inch SAS SSDs will fit?

The FS3600 has 24 bays for 2.5-inch SAS SSD, SAS HDD or SATA SSD drives.

Can the two 10GbE ports and four 1GbE ports connect to my current 1GbE switches without extra adapters?

Yes, the 1GbE ports link directly to 1GbE switches; the 10GbE ports also negotiate down to 1GbE if needed.

How can I confirm the system is delivering the rated 193,000 iSCSI 4K random write IOPS after installation?

Run the built-in iSCSI performance test in DSM and compare the reported 4K random write IOPS against the 193,000 figure.
