Latest QSAN Storage Management System

The Most Reliable Enterprise Storage Solution

QSAN Storage Manager 3 (QSM 3) is a NAS operation system specially designed for QSAN XCubeNAS series. The core of QSM is Linux kernel and in-house fine-tuning 128-bit ZFS. The ZFS has high scalability and can be managed easily, also with the ability to maintain the data integrity. QSM 3 not only inherits the amazing native features of ZFS, its powerful storage features ensure persistent, reliable storage management, protection against data corruption, seamless capacity expansion, several data integrity mechanisms, pool and disk encryption protection, unlimited snapshots, and unlimited clones.

Snapshot

The Safest Data Protection

Snapshot record the status of Shared folders and iSCSI LUNs as changes happened on write. With ZFS snapshots, it's read-only, point to time copy of a file system. By the instantaneous creations, administrators can easily take control data version and execute point-in-time recovery on XCubeNAS by flexibly restored methods. ZFS snapshots are ideal for storing many private copies of mostly shared data. With enterprise file system protection, QSM provides point to time Snapshot to prevent disasters and provide data protection.

Snapshot Protection

Most Functional Point-in-Time Data Protection

Support point to time protection for File and Block level.

QSM Snapshot protection, the original and most functional point-in-time copy of block and file system data protection, which offer stability, data scalability, recoverability and high-performance solution. With low-overhead snapshot copies, it can be used while applications are running and create copied just in one second, regardless of shared folder or iSCSI LUN capacity. With maximum 4096 snapshots per system, instantly, to create writable online backups from any disasters. Snapshot technology dramatically improves the frequency and reliability of backups for a single file to a comprehensive disaster recovery solution.

Snapshot Replication

Powerful Centralized Data Management

Speedy Multi-protection and flexible replications for different structures.

By empowering tap backup retention policy, GFS helps system administrators maximum the amounts of snapshots version but also use the storage capacity even more efficiency. 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 policy in snapshot rotation. IT can modify the frequency to suit the company demands. The weekly or Son backups can set to rotate on a weekly basis with one graduation to Father status each month. The monthly or Father snapshots can set as 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 backup weekly to the primary copy, create a particular copy for the monthly full backups and create another particular copy for the yearly full backups.

Snapshot Retention

3x Longer Protection Time

By setting the GFS rotation policy, You can perform incremental backups daily and full backup 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 recovering files effectively. Snapshots single file recovery provides the flexibilities methods for IT to transfer file in local, remote and even public cloud service.

XMirror

Flexible Protection

Snapshots record the status of Shared folders and iSCSI LUNs as changes happened on write. With ZFS snapshots, it’s read-only, point to time copy of a file system. By the instantaneous creations, administrators can easily take control data version and execute point-in-time recovery on XCubeNAS by flexibly restored methods. ZFS snapshots are ideal for storing many private copies of mostly shared data.

One-way Sync

1-way (unidirectional): data modification of the local NAS will be synchronized to the remote, but any data modification of 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

XMirror is one of the functions of QSM 3.0. It regularly synchronizes a volume or the contents of a folder between multiple XCubeNAS devices, any modification to documents will be replicated to other XCubeNAS via QSM. By using XMirror, data on different XCubeNAS systems, data consistency and availability is ensured. XMirror supports Volume and Folder mirror and up to 64 versions control .

Backup Data to Cloud

Multiple Cloud Services

What if you don’t have a remote server or NAS to back up your data to? Never fear!! Cloud backup ensures that you can backup your data to multiple cloud services such as, Amazon S3, HiCloud S3, Alibaba OSS cloud, and S3 compatible services. This yet another way that XCubeNAS helps you to keep your data easy to be managed between Clouds and local devices.

File Retention

Privacy Management & Capacity Utilization

  • Profession Privacy Management
  • Flexible Capacity Utilization

With organizations managing so many threats to the security of data, backup and recovery systems continue to be very important aspects of data protection. How long data should be kept for is still a question the industry continues to ask. Data retention, describes the continued storage of an organization‘s data for compliance or business reasons. Industry standards and legislation may mandate long-term data retention. Most of the organizations keeps the file from the beginning days until now. However, not each data are really useful for nowadays operation. By setting folders for a retention period it helps storage to be used in the right place.

The New RAID Z3

The Most Safety RAID Level

  • Ultralize system reliabilty for giant storage
  • 1.5x safety than RAID 6

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 device 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, to repair 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 a failed drives are increasing, and at the same time, the lengthening duration of a scrub means that errors are more likely to be encountered during repair. With RAIDZ2 (similar to RADI-6) increasingly unable to meet reliability requirements, there is an impending but 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)

High-speed Network Technology

Fibre Channel Introduction

Fibre Channel (FC) is a high-speed network technology providing lossless delivery of raw block data, at a rate of 16Gb/s. It typically runs on optical fiber cables within and between servers, switches, and storage servers, but can also run on copper cabling.

Multipath I/O (MPIO)

Multipath I/O (MPIO) is designed to mitigate the effects of connection failure by providing an alternative data path between servers and storage devices.

High Reliability

It is vital to have a failover and load balancing configuration when deploying virtual storage solution in your IT environment.

Cutting-edge Performance

Base on 64K sequential throughput up to 3120+ MB/s read and 3050+ MB/s write performance of 16Gb Fibre Channel.
