Users can create multiple user accounts and share folders, and authorized by those shared folders with the support of privilege settings. There are features that IT administrators can set the access control with QSM 3.0.
          • Privilege setting: You can set user’s windows permission of a specific share folder and its subfolder, or limit the user to access specific services.
          • User and folder quota: You can decide the storage space on the individual user folder and limit the storage capacity in each volume.
Efficient Management & Maintenance
With the powerful QSM 3.0 file system and intuitive interface, IT administrators are able to efficiently manage account, storage, and network bandwidth and monitor the activities occurring on the XCubeNAS, and react on a moment’s notice if something goes wrong.
Advanced Storage Pool Technology
QSM 3.0 tailor-made storage pool technology effectively caters to diverse storage demands on data integrity, scalability, high performance and availability. Comprehensive RAID levels are supported to ensure data integrity under every application scenario. Pool capacity could be expanded on the fly, rapidly responding to growing needs for capacity. The design of the QSM allows for creating customized storage pools and auto categorization of data based on usage. “Hot” data will be moved to front line storage while “cold” data is stored on slower disks. All this is done automatically with the QSM.
Wide RAID Type Support and Instant RAID
QSM 3.0 provides comprehensive RAID levels, 0, 1, 5, 6, 10, 50, and 60 for various application scenarios. Each RAID type can be instantly deployed with no initialization or synchronization phase, delivering safe, protected, and high-performance storage space without any delays.
Fast Rebuild
When a drive fails in a RAID set, the QSM is capable of rebuilding the data blocks that have been used, and not the entire RAID set. This helps reduce the risk of data loss during the rebuilding process.
Virtualization Ready
QSM 3.0 is VMware® Ready™, Citrix® Ready™, and Microsoft® Hyper-V™ certified. No matter which virtualization environment you’ve adopted, QSM is a practical and efficient system for you to deploy in any virtualization platform. QSAN’s XCubeNAS can be used for primary storage repositories and as a backup to existing primary storage. As a backup storage device, the XCubeNAS with QSM supports a comprehensive list of 3rd-party virtual machine backup software to ensures that your VMs and data are never at risk of loss.
All-in-One Business Solution
Since having a dedicated machine for each specific task rapidly becomes an expensive and inefficient solution, QSM allows you to enable comprehensive applications and services on your XCubeNAS, whenever you need them. Everything from file sharing to data storage, even hosting a website, QSM can do it all.
IP SAN / NAS Unified Storage
QSM has the performance and the stability for intensive media editing by a single user or by a group of users. The power of QSM can also make the XCubeNAS to be an IP surveillance storage. In the surveillance world, recording every frame is of utmost importance. QSM has the power and stability to record every frame sent to it without any problems.

Enterprise Features to Optimize Your Need
QSM comes with many enterprise features to achieve high reliability, security, and performance. QSM 3.0 adds more exclusive enhancements and features to maximize efficiency, performance, and to ensure around-the-clock services.
User Defined Pool
Thinking ahead to common usage situations, QSM provides three optimized solutions for pools to achieve high performance and availability for dedicated storage applications:
           • Generic: Default type for generic file service or backup usage.
           • Media: Optimize IOPS for small packets of sequential RW and throughput for large, random packets.
           • Database: Data is synchronized between the memory cache and disks in real time for assurance of database Integrity.
Smart Auto-tiering
Auto-tiering helps increase the performance of your business application without crippling your budget. QSM features auto-tiering technology which makes the system continuously analyze the accessing frequency of your data for better data transmission. The most frequently used data will move to higher speed tier, on the other hand, the less commonly used data will move to capacity tier. Demanding workloads of your business applications could be dramatically reduced, and the performance increased without massive investment in expensive all flash storage devices – this is all done by QSM’s intelligent auto-tiering technology.
Access Data Faster With SSD Cache
SSD cache is a large secondary cache that boosts data access speed. The XCubeNAS delivers additional PCIe and SATA SSD slots, enabling you to add SSD without occupying existing HDD slots. QSM 3.0 with SSD cache can enhance the performance of your demanding applications as well as the overall system workflow. Read/write operations across local host and JBODs are greatly enhanced, and the I/O latency of workload-intensive applications which need frequent random access will be greatly reduced.
Thin Provisioning
“Take whatever you need.” That’s the philosophy of thin provisioning. Thin provisioning lets various services and applications use the same storage space without limiting how much of the quota can be used by each. With thin provisioning, space resources are dynamically distributed to the most demanding, responding to your business applications with higher flexibility and promising potentials.
Data Deduplication
The QSM data deduplication feature is an in-line, block-level function that checks the block similarity of data as it enters the system. When duplicated blocks are found, they are not written to the disk, therefore saving space.
Data Compression
With compression, data will be compressed into fewer bytes on transmission to ensure faster transfer speeds and save storage space.
Centralized Data Storage & File Sharing
QSM provides lightning fast and secure ways to share files with anyone, anywhere. You can explore, organize, and move files between your computer and XCubeNAS via QSM, all the while, being able to customize access rights to enhance security. A seamless integrated system allows for file sharing across different computing environments, including Windows, Mac, Linux, Android, and iOS.
Quota Control on Accounts and Share Folders
Take control of your storage space! QSM enables you to add quotas (limits) to the amount of data a user can store. Users can be limited on how much data a folder can store or the quota can apply to the entire system, thus empowering the admin with complete control of what is stored on the XCubeNAS.
Windows AD and LDAP Directory Services
By supporting Windows AD and LDAP, QSM 3.0 enables seamless account integration. Up to 200,000 domain accounts can be joined onto the XCubeNAS and their Home folder is automatically created via QSM, helping IT administrators reduce duplicated sets of credentials and minimizing their workload in giving default account settings and new user setup.
Windows ACLs and Advanced ACLs
Access Control List (ACL) is a permission list specifying what actions specific accounts take on folders and files. Advanced ACL lets you set permissions on subfolders, whereas Windows ACL enables you to apply Windows file permission mechanisms on files and folders. With both kinds of ACL supported, IT administrators can flexibly regulate file access rules no matter what operating system they use, protecting your data from unauthorized access or theft.
Powerful Web File Explorer – File Manager
Connect/share files via the web from anywhere in the world. QSM 3.0 eliminates either physical gaps or virtual boundaries to provide a secure, flattened platform that enables your data to be easily accessed from anywhere at any time via the internet, with maximum security. You can explore, organize, and move files between your computer and the XCubeNAS via QSM, while being able to customize access privileges to enhance security. The integrated system also allows for file sharing across different computing environments, including Windows®, Mac®, Linux®, Android, and iOS platforms by supporting multiple file access protocols including FTP, SAMBA, CIFS, AFP, NFS, and WebDAV.

Real-time Remote Replication
With QSM 3.0, data copies can be distributed to your trusted storage locations through real-time remote backup. By periodically copying data to different branches, your data can be recovered in the unfortunate event that a disaster happens. Data availability is ensured, offering businesses more options for a contingency and recovery plan.
Snapshot & Replica
Snapshots record the status of shared folders and iSCSI LUNs as changes happen on write. By periodically taking snapshots, administrators can better control data versions and execute point-in-time recovery on folders and LUNs. These can be flexibly restored to previously known good states. Replica can transport the version information to the target XCubeNAS via QSM, enabling administrators to utilize storage space based on their retention policies and space requirements.
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.
          • Support Volume and Folder mirror.
          • 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.
          • 2-way (bi-directional): any data modification of a NAS will be synchronized to the others.
          • Version control (64 versions).
Amazon S3 Backup
QSM 3.0 comes integrated with Amazon’s award-winning enterprise cloud service, Amazon® S3, which enables users to back up the whole array to a remote site instead of another XCubeNAS or devices.
Build Your Own Cloud
Using Google Drive, OneDrive, and Dropbox with QSM 3.0, you can build a hybrid cloud which allows you to access and backup the files on mobile devices, PCs, or thin clients anytime and anywhere. The XCubeNAS can be a cloud gateway to bridge your public cloud and private content and act as a central access point.
Security & Data Protection
The growing tide of data breaches, leaks, and malicious software means your data security systems and procedures are vital. Our QSM 3.0 was built on a security-first ideology: full protection of your data. Tools are provided to protect the system from hacking, and interception of data, theft, and accidental deletion. Furthermore, using the inbuilt Anti-Virus, you can add tasks, scanning the entire NAS or the selected folder with specific schedule.
Write Once Read Many (WORM)
WORM technology is designed to prevent intentional or accidental modification of data in a certain period. Files and folders under WORM’s protection can only be read in a user defined period and is unable to modify any files or folders until the period has expired. WORM can protect your data from encryption-based ransomware that installs covertly on a victim’s system and encrypt their files, making them inaccessible. WORM will protect your confidential data from unauthorized modification and threat, ensuring the correctness and integrity of your data.
Self-Encrypting Drive (SED)
XCubeNAS can be safer than you can image with the disk self-encrypting technology called Self-Encrypting Drive (SED). With this technology, even if the physical drive is stolen or misplaced, the data on it remains protected against data breach by generating the authentication key (AK) to prevent unauthorized access. However, the SED offered by QSM 3.0 provides the secured pools migration between different XCubeNAS and is easy to manage the key by exporting AK for more efficiency.
Pool Encryption with AES-256
QSM 3.0’s pool encryption mechanism ensures secured storage environment for any user who wants to modify data by requiring them to first pass authentication. The QSM supports up to AES 256-bit encryption for internal drives and external USB/eSATA drives, and adopts a military level FIPS 140-2 validated encryption, which is considered to be the highest security certification for compliance.
The built-in antivirus function periodically scans files automatically quarantining suspicious files to protect the system from potential threats.
