RackStation RC18015xs+ / Expansion Unit RXD1215sas
Synology high-availability cluster integrates two RackStation RC18015xs+ as dual computing nodes and multiple Expansion Unit RXD1215sas as shared storage units, providing the secure, reliable, and superior-performance network attached storage solution for enterprises seeking uninterrupted service with comprehensive business applications. Synology RC18015xs+ and RXD1215sas are backed with Synology’s 5-year limited warranty.
Reliable Active/Passive Failover Cluster
Uninterrupted availability is critical for businesses. However, server component, environmental problems, human errors, or system malfunctions happen sometimes that might lead to service interruption and raise the cost of running businesses.
Synology high-availability (HA) cluster solution is born to alleviate this problem by combining two RackStation RC18015xs+ and multiple Expansion Unit RXD1215sas as one HA cluster. The two RC18015xs+ computing nodes provide Active / Passive automatic failover. If the active server suffers a malfunction, the passive server is able to provide quick relief by taking over all the running services. All applications and services continue to run without interruption, ensuring high levels of availability.
The connected RXD1215sas acts as the shared storage pool of the two servers, so no data replication is required, saving more energy and rack spaces. The storage capacity is expandable by adding more RXD1215sas (up to 15 sets) to the HA cluster, providing the scalability up to 180 HDDs and a maximum raw capacity beyond 1 petabyte.
Btrfs: Next Generation Storage Efficiency
RC18015xs+ introduces the Btrfs file system, bringing the most advanced storage technologies to meet the management needs of modern large scale businesses:
? Built-in data integrity check detects data and file system corruption with data and meta-data checksums and improve overall stability.
? Flexible Shared Folder/User Quota System provides comprehensive quota control on all user accounts and shared folders.
? Advanced snapshot technology with customizable backup schedule allows up to 256 copies of shared folder backups without occupying huge storage capacity and system resources.
? File or folder level data restoration brings huge convenience and saves time for users who wish to restore only the specific single file or folder.
? Cloud Station with file versioning reduces down to half of storage consumption when compared with Ext4 file system.
Superior Performance
RC18015xs+ delivers superior performance at over 2,270 MB/s throughput and 355,400 IOPS with dual 10GbE connection using link aggregation. Through advanced flash technology, the combination of hard drives and SSD cache boosts throughput efficiently while minimizing cost per gigabyte.
In addition to the default 4 Gigabit ports, RC18015xs+ comes with one PCIe 3.0 x8 slot (running at x8 mode), allowing installation of one 10GbE network interface card (NIC) for maximized bandwidth.
Equipped with 8GB ECC RAM and up to 32GB expansion support, RC18015xs+ ensures data accuracy as well as superior performance to provide a rigorous foundation for the mission-critical tasks of your businesses.
Various Reliability Mechanisms
In addition to the active / passive server design, both RC18015xs+ and RXD1215sas come with redundancy of key system components including power supply units, SAS modules, SAS connection cables, system fans, LAN ports, even the Heartbeat link. In case of failure, the system components are designed for easy replacement and further reduce the chance of system down-time.
Virtualization Certified
RC18015xs+ provides seamless storage solutions for virtualization environments, including VMware®, Citrix®, and Hyper-V®. Being VMware vSphere® 5 and VAAI® integration certified, RC18015xs+ helps offload specific storage operations and optimizes computation power for unparalleled performance and efficiency in VMware environments. As the centralized storage of a virtual environment, RC18015xs+ enables virtual machine migration, allowing movement from server to server whilst eliminating service downtime and disruption to user. Windows® Offloaded Data Transfer (ODX) and Synology Advanced LUN support extremely improves the efficiency on massive data transfer and migration. Synology Snapshot Manager offers better support to servers under VMware vSphere or Windows environment. IT managers can expect guaranteed VM status and data consistency in its highest form.
Comprehensive Business Applications
Powered by the innovative Synology DiskStation Manager (DSM), RC18015xs+ comes fully-equipped with applications and features designed specifically for large-scale business:
? Easy integration with existing business network environments through Windows® AD and LDAP directory services without recreating user accounts.
? Windows ACL support provides fine-grained access control and efficient privilege settings, allowing RC18015xs+ to fit seamlessly into current infrastructure.
? Built-in backup applications protect information assets by regularly backing up files and iSCSI LUNs locally and remotely.
