Synology Introduces PAS7700, an All-Flash Storage Server with Active-Active Dual Controller

Synology has introduced the new storage server PAS7700, the company's first fully SSD-based platform with an active-active dual controller architecture, ensuring consistent operational continuity without interruptions.

Synology PAS7700: When Downtime is Not an Option

The Synology PAS7700 features an active-active dual controller architecture: this means that two servers are effectively present within the same chassis, both always operational; if the primary one encounters any issues, the secondary one immediately takes over, thereby ensuring there are no interruptions of any kind. The advantage, compared to active-passive controllers, is that there is no need to wait for the secondary controller to boot up and take control.

Inside the 4U chassis, the PAS7700 has 48 NVMe U.3 SSD slots (exclusively branded Synology, as listed on the official page), capable of accommodating up to 1.65 PB of total capacity, with the possibility to further expand storage capacity with seven external PAX224 units. The server can be equipped with a maximum of 2 TB of RAM (1 TB per module) and 100 GbE connectivity, allowing it to reach 2 million IOPS with sub-millisecond latency and throughput of up to 30 GB/s. It supports file sharing protocols (SMB, NFS) as well as block protocols (iSCSI, Fibre Channel, NVMe-oF).

To ensure maximum reliability, the PAS7700 offers triple parity RAID, synchronized write protection in memory, and failover at both IP and protocol levels. It also includes all the classic features offered by DSM, Synology's operating system, such as WORM folders, shared folders, immutable snapshots, and backup management with Hyper Backup.

In summary, the Synology PAS 7700 is designed for applications where service downtime is not an option, such as in the healthcare field.
