If you want to securely save data across multiple servers in a iSCSI SAN environment, the Drobo 36TB B1200i iSCI SAN Storage Enclosure (12 x 3TB HDD) is a powerful, 12-bay, easy-to-use means of doing so. This Drobo includes twelve enterprise-class 3TB hard disk drives that have the fast SAS 6 Gbps interface and that offer a total capacity of 36TB. Even with these drives, the enclosure's capacity can be constantly expanded because its twelve drive bays can hold SATA I or II, SAS, or SSD drives of up to 4TB apiece.
Built on the proven BeyondRAID technology, this Drobo delivers advanced capabilities such as thin provisioning and data-aware tiering, usually reserved for more expensive enterprise solutions. Thin-provisioning allows you to expand capacity by switching out one drive with another. Data-aware tiering is a technology that optimizes the use of Drobo SAN storage, depending on the kind of database needs that you have. It also allows you to use SAS, SATA, Solid State drives all in the same enclosure!
For business, this Drobo is designed to provide reliable and high performance storage to servers running business-critical applications such as back up, email, and server virtualization. Drobo B1200i connects seamlessly to your existing TCP/IP network and utilizes the industry-standard iSCSI protocol to provide simple, consolidated storage for your servers. This particular Drobo includes three Gigabit Ethernet ports for connecting to your network and one additional Gigabit port for out-of-band management.
Drobo can protect from single or dual drive failures and has a virtual hot spare capability - ensuring all drives are used at all times. BeyondRAID provides these enhancements over traditional RAID:
•Thin Provisioning as a fundamental capability allows for infinite capacity expansion by just replacing a drive with a larger one
•Instant Expansion occurs when a new, or larger, drive is inserted without any disruption in service
•Mixed Drive Utilization allows you to insert any drive, of any size, or any type, and Drobo will optimally use it - check out our interactive Capacity Calculator
•Automatic Protection Levels ensures the best algorithm is used to protect from drive failure depending on the number of drives that are inserted without any user configuration
•Dual Disk Redundancy enhances BeyondRAID protection by guarding from multiple drive failures
•Virtual Hot Spare utilizes all drives at all time - no drives sitting idle waiting for one to fail
•Drobos are Data Aware, intelligently handling data for added resiliency, performance, and management
•Drive Re-ordering allows Drobo disk packs to be moved to another Drobo, and even re-ordered, while still functioning - try that with RAID
The intelligence built into the Drobo model B1200i allows it to do Data-Aware Tiering, optimizing data layout and drive usage for "hot" requests. Providing faster access to frequently requested information will improve performance of Exchange, SQLServer, and other transactional applications that read and write lots of small data chunks.
With an iSCSI SAN, centralized storage is provided to each server over a high-speed network and storage can be allocated or expanded instantaneously. Also, any single server does not tie up free space and there are fewer storage devices to maintain.
