Reliable Active/Passive Failover Cluster

System and service 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 suers a malfunction, the passive server is able to provide quick relief by
taking over all the running applications and services, ensuring high levels of availability.

Active server

Shared Storage

(Up to 15 units)

Passive server

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.

The Btrfs le system brings storage
management to the next level by
providing more ecient storage utilization,
scheduled shared folder snapshot, and le /
folder-level data restoration.

Btrfs: Next Generation Storage Efciency

RC18015xs+ introduces the Btrfs le 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 le 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 specic single le or folder.

● Cloud Station with le versioning reduces down to half of storage

consumption when compared with Ext4 le 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.4 Through advanced ash

technology, the combination of hard drives and SSD cache boosts throughput eciently
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 Certied

RC18015xs+ provides seamless storage solutions for virtualization environments, including
VMware®, Citrix®, and Hyper-V®. Being VMware vSphere® 5 and VAAI® integration
certied, RC18015xs+ helps ooad specic storage operations and optimizes computation
power for unparalleled performance and eciency 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® Ooaded Data Transfer (ODX) and Synology Advanced

LUN support extremely improves the eciency on massive data transfer and migration.
Synology Snapshot Manager oers 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 specically 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 ne-grained access control and ecient

privilege settings, allowing RC18015xs+ to t seamlessly into current
infrastructure.

● Built-in backup applications protect information assets by regularly backing up

les and iSCSI LUNs locally and remotely.
