Seagate Business Storage NAS
The front of the system has twelve status LEDs, one for each drive, and one for each Ethernet port. A system ID LED blinks orange to show which NAS you are working on. This can be activated either through the button or in the browser software. Openings on each side allow fresh air to flow through the system; over the drives first, then the other internal components.
A single USB port on the front allows system admins to quickly backup flash drives. There are three buttons on the front as well. From left to right, a power button, a system identification, and an alarm mute button.
A convenient pull-tab lists the two MAC addresses.
Seagate packs a lot of redundant features on this system. Dual power supplies and dual Ethernet ports give the NAS high availability. On the far left is another system identification button that activates the front LED.
Keyboard, mouse, USB, console, and VGA ports are on the back of the system for easy access to advanced user customizations.
The secret to the system is a mid-mount backplane. A drive bay number is etched in each section as well as on the backplane.
To reduce the width of each drive, the drive sled is designed for vertical inserts and not the typical horizontal installs we are used to seeing. The plastic handle keeps the drive secure in the SATA connector.
The system can operate with two fans working, and they are hot swappable.
The top cover is toolless; two-pull tabs release the tension loaded top door. This allows you to quickly replace drives or fans.
Inside we found a large passive copper heat sink just behind the three fans.
Not leaving anything to chance, Seagate hot glued the SATA cables in place.
To my surprise, the system is very quiet, even by consumer NAS standards. With the fans deep inside the system, the fans are nearly silent even under heavy use.
The power supplies are from Delta Electronics and are purpose built 1U NAS power supplies. If there is a weak point in the hardware, the power supplies are it. These units are rated EPA level white or 80-Plus White, one-step lower than 80-Plus Bronze. At 50% capacity they are around 84% efficient.
Installing the NAS is easy using the hardware provided by Seagate. The flat screws allow the NAS to sit fully against the rack rails.
Here we see the drives installed with the cover off. The slides allow the NAS to pull out beyond the top cover opening and then some. If you have a server above the NAS with long handles, the NAS comes out far enough to still remove the cover.
