RAID 0 - Speed
RAID 0 mode provides disk striping across all drives in the RAID drive group. RAID 0 does not provide data redundancy but does provide the best performance of any RAID levels. RAID 0 breaks up data into smaller segments and stripes the data segments across each drive in the drive group.
RAID 1 - Data protection
Set the system to data protection mode (also known as mirrored mode or RAID 1) and the capacity is divided in half. Half of the capacity is used to store your data and half is used for a duplicate copy. If one drive goes down your data is protected because it's duplicated.
RAID 5 - Data protection and speed (available on 4-bay NAS)
In systems with three or more drives we recommend that you set the system to RAID 5. This gives you the best of both worlds: fast performance by striping data across all drives; data protection by dedicating a quarter of each drive to fault tolerance leaving three quarters of the system capacity available for data storage.
RAID 10 or RAID 1+0 - High reliability with high performance (available on 4-bay NAS)
RAID 10 delivers very high I/O rates by striping RAID 1 (mirrored) segments. This RAID mode is good for business critical database management solutions that require maximum performance and high fault tolerance. A system set to RAID 10 yields half the total capacity of all the drives in the array.
JBOD & spanning
JBOD is the use of one or more drives not in a RAID configuration but managed as separate logical volumes. Spanning is the combination of drives in a linear fashion to create one large logical volume. The advantage of using this mode is that you can add more drive without having to reformat the system.
User management/group management
With My Cloud Expert Series, it is easy to grant users access to the NAS, create groups and give access to those groups, and manage the amount of storage users/groups have access to.
Microsoft Active Directory support
Add My Cloud Expert Series to your Active Directory (AD) server for simplified and centralized management, as well as easy access for colleagues with one set of domain accounts. Everyone can use a single account to access various services with ease.
Distributed File System (DFS)
Connect My Cloud Expert Series NAS to a Microsoft Windows server to organize many distributed SMB file shares into a DFS for improved data availability in the event of failure or heavy workloads.
Volume virtualization using iSCSI targets
Manage storage over long distances and transfer data over LANs, WANs or the Internet by creating a Storage Area Network (SAN). My Cloud Expert Series NAS allow you to create and manage iSCSI targets, similar to a local hard drive, that is accessed over a network rather than locally. The iSCSI target is protected by the underlying RAID structure of the My Cloud Expert Series NAS.
Jumbo frame support
My Cloud Expert Series support jumbo frames up to 9000 bytes. These large IP frames are used to increase performance over supported networks. Increases in data transfer speeds only occur if every device on your network supports jumbo frames.
Link aggregation and failover support
Combine multiple network connections to increase data transfer past a single connection and provide redundancy in the event of a failed connection. This is also known as bonding, and refers to the use of two LAN NICs present in your NAS and two cables connected to your router simultaneously, improving reliability.
My Cloud Expert Series support iPv6, keeping your NAS up-to-date with the latest Internet Protocol.
UPS support (USB and network)
USB UPS: A supported UPS device that is connected to a My Cloud Expert Series NAS via USB cable can detect a power loss and gracefully shut down power.
Network UPS: Network UPS devices can be used when there is a single UPS device and multiple My Cloud Business Series units. One My Cloud Expert Series NAS can act as a "Network UPS server" and connect to the UPS device via USB or network (depending on the device). The network UPS server obtains UPS information and relays it to the other "client" Expert Series NAS.
Real-time resource monitors
Provide up-to-date information on My Cloud Expert Series resources, including CPU percentage, network utilization and RAM usage.
Virtual volumes simplify scalability by allowing you to map iSCSI targets on other network storage devices and present them as shares on your My Cloud Expert Series device.
Simple Network Management Protocol, a protocol for managing devices on a network, allows My Cloud Expert Series NAS to be used in a managed environment. IT administrators who need to monitor multiple network devices, including My Cloud Expert Series via SNMP should download the document available.
