terastation nas systemTERASTATION NAS SYSTEM

TeraStation 3000 runs on Buffalo's TeraStation NAS System providing a host of business-class features from network file sharing and security to RAID management, remote access and more. Managing data, backups and data sharing in a production environment or larger business is made easy with this NAS operating system. Included on all Buffalo TeraStation devices, TeraStation NAS System simplifies your everyday data needs.

data protection and backupDATA PROTECTION AND BACKUP

TeraStation 3000 is bundled with eleven licenses of NovaBACKUP Buffalo Edition (one server and ten workstations), providing a complete, all-in-one data protection solution for PCs and Windows® servers.

Additionally, TeraStation 3000 features Buffalo's replication technology providing easy and high performance data replication from one Buffalo NAS device to another Buffalo NAS device over the network or the Internet. This offers real-time synchronous replication of data, providing easy, continuous data protection in the event of data loss. If your system configuration includes data replication from one TeraStation 3000 unit to another, you can set up fail-over to automatically switch main operation over to the redundant TeraStation if the main unit ever becomes inaccessible. Within one minute, the backup TeraStation automatically assumes the role of the main TeraStation 3000 with no disruption and no IT intervention. Data can be continuously accessed without any notice of the failover.

reliable and secure network storageRELIABLE AND SECURE NETWORK STORAGE

TeraStation 3000 offers high capacity, highly available storage accessible among multiple platforms for seamless centralized storage and backup. Create user and group profiles and control folder and file access to protect business critical content and privacy.

Support for multiple levels of RAID provides continuous data protection and increased fault tolerance and data availability.

  • RAID 0 combines all drives into a single array offering maximum capacity with no redundancy
  • RAID 1 mirrors two arrays, creating an exact copy of data for fault tolerance
  • RAID 5 stripes the data across all four drives, interspersing parity data to provide an efficient blend of fault tolerance and storage capacity
  • RAID 6 stripes the data across all four drives but with double distributed parity, allowing up to two drives to fail without suffering data loss
  • RAID 10 mirrors two sets of hard drives and combines them into a single array, striping data across all mirrored sets for fault tolerance and increased performance

port trunkingPORT TRUNKING

TeraStation 3000 allows for the trunking of two Ethernet ports, providing both higher performance by utilizing the bandwidth of both ports simultaneously as well as fault tolerance in the event of a port failure.

remote file accessREMOTE FILE ACCESS

TeraStation 3000 offers multiple ways to remotely access and share your important data for enhanced collaboration and productivity. With WebAccess and FTP/SFTP servers, you can securely access and share files with anyone outside the local network. Trusted recipients can access selected files from anywhere over the Internet, and with WebAccess files can also be accessed remotely from tablet and smartphone devices.

hot swap hard drivesHOT SWAP HARD DRIVES

TeraStation 3000's hot swap feature allows a user to replace a hard drive in the event of failure without powering down the device.  Simply remove the defective drive, insert the new drive and the data rebuilds while still being available to clients on the network with zero downtime.

hot spare hard drivesHOT SPARE HARD DRIVE

TeraStation 3000 allows for one of the hard drives in the array to be designated as a hot spare.  In the event of a hard drive failure, the hot spare hard drive will automatically be rebuilt with the information contained on the failed drive with seamless data accessibility to clients on the network.

storage virtualizationSTORAGE VIRTUALIZATION

Configure TeraStation 3000 as an iSCSI target to add affordable virtualized storage to your business network. Storage virtualization serves to decrease IT spending by maximizing the resources offered by modern servers while providing affordable server scalability and reliability. A virtualized environment removes a significant amount of server dependence, shifting the burden to the storage devices.
