Synology – Announcing the RS1619xs+

Synology RackStation RS1619xs+ is a high-performance 1U rackmount NAS with comprehensive storage,
data backup, and collaboration applications, suitable for small- to medium-sized businesses. RS1619xs+
simplifies data management, optimizes virtualization environments, and rapidly expands storage capacity
with minimal time investment in setup and maintenance. Synology RS1619xs+ is backed by Synology’s
5-year limited warranty.
Powerful NAS Solution in 1U Form Factor
Synology RS1619xs+ is a 1U 4-bay rackmount network attached storage solution
equipped with a quad-core processor, 8 GB DDR4 memory (expandable up to 64
GB), and four Gigabit LAN ports. With an optional 10GbE network adapter card installed,
RS1619xs+ delivers sequential reading throughput over 1,523 MB/s and 162,097
iSCSI random read IOPS under a RAID 5 configuration1.
RS1619xs+ comes with two onboard M.2 SSD slots, allowing fast system cache
creation with M.2 2280 NVMe/SATA SSDs without occupying internal 3.5″ drive bays.
RS1619xs+ also provides great flexibility to easily scale up to 16 drives when connected
to one Synology RX1217/RX1217RP expansion unit2. Storage capacity can be
expanded according to your business needs with minimal effort.
Enterprise-Grade Applications
Powered by the innovative Synology DiskStation Manager (DSM), RS1619xs+ 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.
• Windows ACL support provides fine-grained access control and efficient privilege
settings, allowing RS1619xs+ to fit seamlessly into existing 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 ensures
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.

Btrfs: Next Generation Storage Efficiency
RS1619xs+ 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 shared
folders to be backed up in a minimum 5-minute interval, without consuming heavy
system resources.
• File and 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 and User Quota System provides comprehensive quota
control on 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, and 10.
• A cutting-edge iSCSI service built for IT administrators that offers advanced LUN and
provides lightning-fast snapshot creation, recovery, and cloning.
Virtual Machine Manager
RS1619xs+ is designed with virtualization in mind. Virtual Machine Manager enables
you to test new software in sandboxes, isolate your customers’ machines, and increase
the flexibility of your server.
• Virtual DSM provides an equally intuitive experience as DiskStation Manager, offering
a reliable storage solution with robust features.
• Various Operating Systems Support lets you run Windows, Linux, and Virtual DSM
on your Synology NAS in just a few steps.
• Snapshots for Virtual Machines is a snapshot technology provided by Virtual Machine
Manager, allowing you to perfectly clone and restore a virtual machine within seconds.
• Live Migration lets you seamlessly migrate Virtual DSM instances from one Synology
NAS to another.
• Flexible IT Resource Management allows you to allocate hardware resources like
computing power, storage space, or network interfaces across several virtual machines.
• Multi-Tenant Environments allow you to create multiple isolated virtual machines for
subsidiary business units or departments.
• Synology iSCSI Storage fully supports most virtualization solutions to enhance work
efficiency with a simple management interface.

powerful information management and interaction features.
Reliability, Availability & Disaster Recovery
System reliability is critical for businesses everywhere. RS1619xs+ responds to these
concerns with wide-ranging availability and redundancy features:
• Synology High Availability ensures seamless transitioning between clustered servers in
the event of unexpected disasters and ensures that your services remain online.
• Snapshot Replication provides schedulable, near-instantaneous data protection,
ensuring business documents in shared folders, virtual machines in iSCSI LUNs, or
dockerized application data remain safe and available in the event of a disaster.
• Redundant power supplies, system fans, and network ports with failover support
ensure continual service uptime.
• High reliability system design, including fan-less CPU heat-sink and passive cooling
technology, prevents single points of failure.
