The DS415+ NAS solution has CPU with an AES-NI hardware encryption engine, a floating-point unit, as well as DDR3 RAM. The drive bays accommodate huge amounts of storage capacity, while the USB (Universal Serial Bus) 3.0, USB (Universal Serial Bus) 2.0, & e SATA ports allow users to connect & access a range of external storage devices. Dual LAN ports support failover & link aggregation, thus improving resiliency & potential throughput. DS415+ supports Synology high availability (SHA), harnessing an active & a passive server into one cluster, mirroring written data between the two units. Should the main server malfunction, the passive server immediately kicks in & takes over all running services & data. Synology Hybrid RAID means that you can optimize usage & get the most out of your hard drives, while also keeping your storage safe with data redundancy.
