N8900PRO
High Performance, Full-Featured
2U Rackmount NAS Server
High Availability (HA)
For the rst time, your data is completely free of delays in access. Regardless of the situation, HA actively
keeps your data on two separate, identical NAS. If one needs maintenance, the other will dutifully rise
to the occasion without as much as a blip in service. Whether rain, shine, or Armageddon, your data will
always be there.
10GbE Ready
High-end data centers often need a level of speed that today’s average Internet cannot provide. This
Thecus NAS is 10Gb Ethernet ready to satisfy the toughest needs of today and tomorrow.
Cost Effective
and Wipe
Daisy Chaining
With daisy chaining, users now have the ability to cost eectively increase their storage volume while
maintaining fast transfers. To set up a daisy chain, one master NAS unit is installed as a controller with
up to four DAS linked as slaves. SAS cables are then used to link the units together in order to ensure
rapid speeds. The ability to reach tremendous capacities while saving nearly 30% on hardware costs
(versus traditional storage architecture) is something truly groundbreaking in the industry.
7 modes of link aggregation supported
Link aggregation can sustain multiple network connections and provide redundancy in case one of the
links fails. Thecus NAS supports 7 modes which provide Load Balance, Failover, 802.3ad, Balance-XOR,
Balance-TLB, and Balance-ALB, Broadcast.
Disk Clone and Wipe
Disk Clone allows users to copy the entire contents of a disk to one or many other disks while Disk Wipe
allows for permanent volume data destruction.
Bundled with FREE Intel Security
Thecus’ innovative hardware helps prevent failures. But sometimes you have to protect the NAS against
itself. Adding an antivirus to the already comprehensive software bundle will provide the necessary
software protection by scanning the les on your NAS and defending it against possible threats.
McAfee is the world’s largest dedicated security technology company and shares Thecus’ spirit of
dedication and quality. By establishing a strong partnership with them, Thecus will allow users the
benet of Intel Security powerful software on their NAS entirely for free.
