QSAN Storage Management 3.1 w/Snapshot Recover & RAID Z3

Smart Snapshot Retention: 4.2x Longer Protection Time

By empowering the tap backup retention policy, GFS helps system administrators maximize the amounts of snapshots version but also use the storage capacity even more efficiently. GFS backup policy a.k.a. Grandfather – Father – Son backup rotation policy. You can set the maximum amounts of snapshot versions to keep, for example, set weekly, monthly, and yearly backup policies in snapshot rotation. IT can modify the frequency to suit the company’s demands. The weekly or Son backups can be set to rotate on a weekly basis with one graduation to Father status each month. The monthly or Father snapshots can be set on a yearly basis with one graduation to grandfather status each year. At the same time, system administrators can lock the particular snapshots to prevent automatic removal by the retention policy. By setting the GFS rotation policy, You can perform incremental backups daily and full backups weekly to the primary copy, create a particular copy for the monthly full backups, and create another particular copy for the yearly full backups.

Single File Snapshot Recover: Most Precision Restore

Snapshots help system administrators assures data security and single file recovery delivers a powerful tool for administrators to reduce the time required for actual failover and recover files effectively. Snapshots single file recovery provides the flexibilities methods for IT to transfer files in local, remote, and even public cloud services.

XMirror: Flexible Protection

One-way Sync

1-way (unidirectional): data modification of the local NAS will be synchronized to the remote, but any data modification of the remote NAS will not be reflected.

Two-way Sync

2-way (bi-directional): any data modification of a NAS will be synchronized to the others.

Multi Nodes Sync

Support multi-devices real-time data synchronization.

The mission of QSM was to simplify storage and to construct an enterprise level of quality from storage components by building smarter software – indeed that notion is at the heart of the ZFS (Zettabyte File System). The most important part of enterprise storage devices is RAID (Redundant Array of Independent Disks). RAIDZ is a data and parity scheme like traditional RAID, but it uses dynamic strip width. Every block is its RAID-Z stripe regardless of block size which means every RAIDZ write is a full stripe write. At the same time, RAIDZ combines with COW (Copy on Write) transactional semantics of ZFS and eliminates the RAID write hole. Nowadays, the time to populate a drive is straight significant for RAID rebuild. As disks in RAID systems take longer to reconstruct, the reliability of the total system decreases due to the increased period running in a degraded state. As hard drive capacities continue to outpace their throughput, the time comes for a new level of the RAID – Triple Party RAID and Beyond. Today, repairing a RAID group can easily take more than a day and the problems are getting significantly more pronounced as HDD continue to outpace its throughput. Ave. 0.8 percent of disk failures would result in data loss to an uncorrectable bit error. Therefore, the time to repair failed drives is increasing, and at the same time, the lengthening duration of a scrub means that errors are more likely to be encountered during the repair. With RAIDZ2 (similar to RADI-6) increasingly unable to meet reliability requirements, there is an impending yet urgent for Triple parity RAID. The data reliability on RAIDZ3 is 5X safer than RAIDZ2 and 30X safer than RAIDZ1(similar to RAID-5)

File Retention: Privacy Management & Capacity Utilization

• Profession Privacy Management

• Flexible Capacity Utilization

With our unique RAID algorithm, QSRAID, designed for SSDs, XCubeFAS dramatically increases the security level of RAID pools by 9.8 times and keeps IT managers free from the worry of pool failure caused by SSD lifecycles. Additionally, with fast rebuild and RAID EE technology support, XCubeFAS can save significant rebuild time and provides users with a faster and more secure environment.

RAID Z3: Supports All New RAID Z3

• Ultralize system reliability for giant storage

• 1.5x safety than RAID 6
