Designed for networks of up to 100 users, the 16.256TB (4 x 4TB HDD, 1 x 256GB SSD) B810n 8-Bay NAS Server from Drobo may be used as a primary storage device for important files and documents, a place to backup files and projects, or as a way of connecting computers on your network. It also provides reliable storage for server applications, email, and data protection while integrating into TCP/IP network infrastructure via SMB and AFP protocols. Additionally, Adaptive Link Bonding brings link failover and link aggregation support support without Ethernet switch support to help increase data throughput and compensate for network connection problems.
The Drobo B810n is powered by a Marvell Quad-Core processor and 2GB of RAM. It has eight 3.5" drive bays which are able to support up to eight SATA hard drives or SSDs, with no tools being required for installing 2.5" SSD carriers. The drive bays also support 4KN disks. Within its eight drive bays, this Drobo B810n is equipped with 4 x 4TB hard drives and a 1 x 256GB SSDs for a total storage capacity of 16.256TB. As SSDs are able to operate with faster data transfer speeds, Data-Aware Tiering migrates the most frequently accessed data to the SSDs, while less accessed data is stored on the hard drives.
The Drobo 810n has also been built on BeyondRAID technology. If there are any empty drive bays, BeyondRAID allows additional drives to be inserted into the array, where they would be automatically configured. If all drive bays are occupied, simply replace the smallest capacity drive with a larger one and BeyondRAID will handle the rest. BeyondRAID is also what allows drives of varying capacities to work in the same unit, which helps enable future expansion as larger drives become available.
Built with a 3U rackmount form factor and controlled using Drobo's Dashboard software, the 810n is powered using an internal 100/240 VAC power supplies that operate at 1.8/0.75 A and 50/60 Hz. It is compatible with Windows and Mac. Included is 1 x 6.0' power cord, 2 x 6.0' Ethernet cables, and international LED labels for the front panel. This NAS server is protected by a limited 1-year warranty.
Unlike traditional RAID arrays, the BeyondRAID technology in Drobo enables different drive capacities to work in the same unit. This enables future expansion as larger SATA drives become available. With Drobo, access to data is always maintained while it protects against simultaneous drive failures
SSD Accelerated Performance
The B810n was designed to provide users with uniform performance. Add two SSDs and you can accelerate performance for simultaneous users. Drobo uses two techniques to accelerate access to your data:
- Data Tiering: as transactional data (small pieces of data) are read or written, they are places into SSD storage. Subsequent reads or writes to these blocks are almost instantaneous, as there is no delay induced by a hard drive's magnetic head having to move into position. Active, or "hot" data is stored in an SSD tier of storage. As it cools, i.e. access decreases, the B810n will move the data to the hard drive tier
- Hot Data Cache: this is a technique to accelerate data reads. As data is read from hard drives, the B810n will pre-fetch nearby data that it predicts will be also be read. Your benefit is faster access and less waiting
