The Arcticroc is a highly versatile RAID system that is available in a 4-bay tower model with large capacity disk storage. The drives are hot-swappable, with transfer speeds of 3 Gbps to and from the host.
Speed and massive storage capacity are typically cited as the prime benefits of RAID storage management. Real-time redundant backup of data and fault tolerance make RAID a critical part of any enterprise, regardless of size. Commercial enterprises that fail to employ (or use) RAID or disk mirroring can face large costs in the event of disk failure. Upon careful analysis, potential adopters of RAID technology will discover that the greatest cost of disk failure is the accumulated long term loss of data and subsequently loss of time and money. Designed for professional users and the enterprise sector, the newly released 4-bay Arcticroc Tower RAID systems help prevents data loss and streamlines storage management.
Arcticroc RAID systems
Using this RAID system is as easy and familiar as using a single bay external enclosure. The need for software GUI installation is eliminated. Onboard LED indicators keep you apprised of system, connection, and Hard Disk Drive (HDD) status while the user-friendly HDD tray design makes HDD hot-swapping effortless from the top end. Two fans blow air through the hard disk drives to dramatically enhance internal air flow and efficiently cool the high speed SATA hard drives within the system.
A Redundant Array of Independent Disks (RAID) is a system that utilizes multiple hard drives to share or replicate data among the disks. Each selected RAID mode (combinations of disks), has its own benefits; data integrity, fault-tolerance, throughput or capacity when compared to single drives.
RAID 0 (striping)
RAID 0 (striping) is a performance-oriented, non-redundant data mapping technique. It combines multiple hard drives into a single logical unit. Instead of recognizing several different hard drives by the host computer, the operating system recognizes only one large drive. Striping splits data evenly across two or more disks simultaneously, dramatically increasing performance.
RAID 1 (mirroring)
RAID 1 (mirroring) consists of at least two drives storing duplicate copies of the same data. In this mode, the data is simultaneously written to two disks. Thus, the storage capacity of a two-disk array is combined into a single disk. In mirroring mode, if one of the disks fails, either source or backup, the data is still available. However, if the source disk fails during the rebuild process, the data in both disks will be lost.
Spanning provides another maximum capacity solution, which some call it as "large". Spanning combines multiple hard drives into a single logical unit. Unlike striping, spanning writes data to the first physical drive until it reaches full capacity. When the first disk reaches full capacity, data is written to the second physical disk. Spanning provides the maximum possible storage capacity, but does not increase performance.
CLONE consists of at least two drives storing duplicate copies of the same data. In this mode, the data is simultaneously written to two or more disks. Thus, the storage capacity of the disk array is limited to the size of the smallest disk.
RAID 5 uses block-level striping with parity data distributed across all member disks. It is also called Parity RAID. Every time a block is written to a disk in a RAID 5 disk array, a parity block is generated within the same stripe. A block is composed of many consecutive sectors on a disk. RAID 5 mode provides decent data protection and fault tolerance. The speed of operation is average in comparison to other RAID modes.
In RAID 1+0, the data is first mirrored and then striped. Under this RAID Mode, it provides another way to achieve higher performance and data security, while increasing complexity. The key difference between RAID 0+1 and RAID 1+0 is that RAID 1+0 creates a striped set from a series of mirrored drives. In a failed disk situation, RAID 1+0 performs better because all the remaining disks can continue to be used. The array can sustain multiple drive losses as long as none of the mirror set loses all of its drives.
Just a Bunch of Disks (JBOD) refers to a group of hard drives. In JBOD, the number of logical drives is equal to the number of physical drives. This mode allows the RAID System to operate as a multi-disk storage enclosure, but provides no data redundancy.
Hot swapProduct Highlights
Hard drive hot swap refers to the ability to add or remove a device from the host computer without powering off the device; the system will automatically recognize the change after the hot swapping is completed.
