Scalable Storage with Outstanding Performance

With the ability to scale up 180 storage drives and deliver more than 1 petabyte of raw capacity, SA3400 can easily fulfill the need for video post-production and massive surveillance deployment. Offering dual built-in 10GBASE-T Ethernet for fast data transmission, PCIe 3.0 slots for expansion of 10G/25GbE network interface cards, and supporting various SAS and SATA drives without vendor lock-in, SA3400 provides an elastic and expandable storage solution with optimized total cost of ownership (TCO).

SA3400 is equipped with an Intel® Xeon® D-1541 8-core CPU and 16GB ECC RDIMM memory (upgradable to 128GB) to ensure system performance and data integrity, delivering over 5,520 MB/s sequential throughput via aggregated 10Gb Ethernet.3 With 5-year warranty, SA3400 guarantees a reliable server, maximizes service uptime, and mitigates business loss caused by unexpected hardware failure.

Effortless Virtualization Deployment

Synology’s Virtual Machine Manager adds boundless capabilities to your NAS. You can set up and run various virtual machines including Windows, Linux, and Virtual DSM on your NAS to test new software versions in a sandbox environment, isolate your customers' machines, and increase the flexibility of your SA3400 with reduced hardware deployment and maintenance costs. Synology iSCSI storage fully supports most virtualization solutions to enhance work efficiency with a simple management interface. VMware vSphere™ 6.5 and VAAI integration helps offload storage operations and optimizes computational efficiency. While Windows Offloaded Data Transfer (ODX) speeds up data transfer and migration rates, the support for OpenStack Cinder transforms your SA3400 into a block-based storage component.

Features:

Small-to-hyperscale flexibility

Scalable up to 180/96 drives delivering more than 1.5 petabytes raw capacity, SA3400 can easily fulfill extensive storage needs, including video pos-production and massive surveillance deployment.
