High-speed Scalable Storage Server

Synology RS3618xs is a 2U 12-bay rackmount network-attached storage solution equipped with a quad-core processor and 8GB DDR4 memory (expandable up to 64GB), meeting the needs for large-scale businesses. With 10GbE Link Aggregation enabled, RS3618xs delivers great performance at over 3,900 MB/s sequential reading throughput and 143,500 iSCSI random IOPS under a RAID 5 configuration. Encrypted data throughput can reach over 2,300 MB/s in reading and 1,177 MB/s in writing

RS3618xs provides great flexibility to easily scale up to 36 drives when connected to two Synology RX1217 or RX1217RP2 expansion units. Storage capacity can be expanded according to your business needs with minimal effort.

Btrfs: Next Generation Storage Efficiency

RS3618xs introduces the Btrfs file system, bringing the most advanced storage technologies to meet the management needs of modern businesses:

• Advanced snapshot technology with customizable backup schedule allows up to 1,024 copies of shared folder backups in a minimum 5-minute interval without occupying huge storage capacity and system resources.
• File or folder level data restoration brings huge conveniences and saves time for users who wish to restore only a specific file or folder.
• Flexible Shared Folder/User Quota System provides comprehensive quota control over all user accounts and shared folders.
• File self-healing: Btrfs file system is able to auto-detect corrupted files with mirrored metadata, and recover broken data using the supported RAID volumes, which include RAID1, 5, 6, 10 and RAID F1.

Comprehensive Business Applications

Powered by the innovative Synology DiskStation Manager (DSM), RS3618xs comes fully-equipped with applications and features designed specifically for large-scale businesses:

• Windows® AD and LDAP support allows easy integration with existing business directory services without recreating user accounts.
• Windows ACL support provides fine-grained access control and efficient privilege settings, allowing RS3618xs to fit seamlessly into current infrastructure.
• Internet file access is simplified by the encrypted FTP server and the web-based file explorer, Synology File Station. HTTPS, firewall, and IP auto-block support ensure file sharing over the Internet is protected with a high level of security.
• Application Privileges controls access to applications and packages based on each individual account, user group, or IP address
• MailPlus allows your business to set up a secure, reliable, and private mail server while giving your employees a modern mail client for receiving and sending messages.

Effortless Virtualization Environment

Synology iSCSI storage fully supports most virtualization solutions to enhance work efficiency with a simple management interface. VMware vSphere™ 6.5 and VAAI integration helps offload storage operations and optimizes computation efficiency. Windows Offloaded Data Transfer (ODX) speeds up data transfer and migration rates, while OpenStack Cinder support turns your Synology NAS into a block-based storage component.

Synology’s Virtual Machine Manager adds unlimited capabilities to your NAS. Set up and run various virtual machines, including Windows, Linux, and Virtual DSM so that you can test new software versions in a sandbox environment, isolate your customers' machines, and increase the flexibility of your RS3618xs with reduced hardware deployment and maintenance costs.
