Ultra-High Performance
Link Aggregation delivers high performance of over 1000 Mbps throughput and 100,000 IOPS under RAID 5 configuration*. In addition to the default 4 Gigabit ports, dual 10 GbE ports are supported with the add-on PCIe x8 Gen2 Network Interface Cards to maximize the system bandwidth. 1
High Reliability & Availability
Reliable functioning of commercial systems is of paramount concern to business users that depend on servers every day. The NAS server now has the fanless CPU heatsink to prevent the single point of failure. With the CPU's passive cooling technology it achieves a high reliability system design. When system detects fan failure, the built-in redundancy mechanism will spin up the functional fan(s) to properly ventilate the system and support continuous operations until the replacement fan arrives. Therefore, potential system damages are minimized and system availability is maximized.

The network ports with failover support combined with hot-swappable drives ensures continual service uptime during drives replacement or unexpected LAN failure. The ECC RAM module detects and corrects errors that occur during data transmission. It supports up to 6 GB ECC RAM and provides secure data protection and performance to face the mission critical tasks of large scale businesses.

Robust Scalability Up to 100 TB
The NAS Server is designed to grow with your business and provides the ability to seamlessly expand a single volume up to 100 TB on the fly. When the storage capacity is nearing its limits, this can be easily expanded with Synology DX1211*. The server is connected via an Infiniband cable that carries 12 Gbps SATA signals to ensure maximum throughput.

The management of large storage space is simple and flexible. Multiple volumes on RAID allow users to create more than one volume on a RAID structure. This provides a flexible and efficient way to manage the storage across all hard drives. When the need for more space arises, the volume can expand without any service disruption. 2

Unified Storage and Virtualization Ready
The DS3612xs NAS Server runs on the novel operating system, Synology DiskStation Manager (DSM), that integrates file level and block level storage in one unified storage system platform thus reducing the total cost for management.

Comprehensive network protocol support (CIFS/SMB, AFP and NFS) assures seamless file sharing across Windows, Mac and Linux platforms. iSCSI is also supported as the ideal alternative to SAN solution for business. The affordable iSCSI allows large scale business to consolidate storage into data center storage arrays while providing hosts with the illusion of locally attached disks. With iSCSI support, it provides a seamless storage solution for virtualization servers, such as VMware, Citrix and Hyper-V. It is also certified with the latest VMware vSphere 5, supporting VMFS-5 and extended storage migration capability with flexibility and higher performance in VMware virtualization platform.

Thin Provisioning is available for file level iSCSI, which enables administrators to oversubscribe provision and then grow storage space whenever required in a safe way. With Thin Provisioning, you can maximize the storage utilization to reduce the total cost of ownership for the storage system.

Full Featured Business Applications
The NAS Server offers applications and features designed specifically for large scale business. Windows ADS and LDAP integration allows it to quickly and easily fit in an existing business network environment without recreating user accounts. Windows ACL support provides much finer grained access control and efficient privilege settings. IT staffs can set up privileges to files and folders through their familiar Windows user interface.

The built-in backup application is provided for backing up data in the DS3612xs to another Synology NAS, expansion unit or any rsync server via an encrypted transmission. It is even possible to back up from DS3612xs NAS Server to the cloud with the Amazon S3 support. Shared folder sync is also available in DSM for implementing disaster recovery plans. With shared folder sync, you are able to replicate data to another DiskStation within the Intranet or across the Internet, thus reducing the risk of business interruption.

Energy Efficient Design
The DS3612xs NAS Server has an energy efficient design. Compared with the average storage server counterparts, it consumes a relatively low amount of power and the hard drives hibernate when they are not in use.

DiskStation Manager (DSM)

Apps on Demand
The Web-Based Platform:
DSM is a web-based platform. This means that you can select the service that you want to use and install the corresponding apps, only when you need it. So you can choose from Photo Station, Download Station, Cloud Station and other web apps to install from Package Center. The total customization gives you more control over your network storage.
Cloud Station
Automatic Sync:
The Cloud Station folder is a private cloud that always prepares itself up-to-date. It pushes files, songs and photos to any PC that you are working on and syncs automatically.*

Offline Viewing:
You can view and edit your files anytime via the Cloud Station folder even without an Internet connection. Now edit spreadsheets, create a new document or upload photos all within the folder offline. After Internet access is resumed, all changes are automatically synced onto Cloud Station and can be viewed offline.

Everybody's Cloud:
A single NAS is everyone's private cloud. Every user can own a Cloud Station folder on their own computers and enjoy all the benefits it has to offer. All clouds are on one DiskStation, where data security and privacy are guaranteed. In addition, when your PC and DiskStation are in the same local area network (LAN), the transfer rate is higher than what is offered over the Internet. You can upload and sync large files faster. 3

Synology ezCloud
QuickConnect Service:
Even without any network settings, you can access your files remotely. With Synology's ezCloud, there's nothing you can't retrieve over the Internet. Once the network cable is connected to your DiskStation, you can use Cloud Station and DS file to access and sync files. There is no need to configure a router or any other network device*.

Personal DDNS:
Control the Internet presence of your cloud with Synology's DDNS service. The ezCloud lets you directly register a personalized domain name from Synology. There are no more hassles of seeking third party service. You can log into the MyDS Center webpage and see the status of your registered Synology NAS.

Stay Connected with Notifications:
You can get notifications on the status of your DiskStation through multiple channels. Synology provides free push services on Skype, Windows Live Messenger and DS finder for iOS devices. You can decide which event notifications to trigger and avoid unnecessary alerts. Event categories can be precisely set to take appropriate action as per your need. 4

Synology Hybrid RAID
Instant Volume Creation and Optimized Storage Capacity:
DSM makes volume creation simple with Synology Hybrid RAID (SHR). You don't need to study the difference between RAID types and requirements. SHR offers instant volume creation and optimized storage capacity.
Unlike traditional RAID that creates volume based upon the smallest hard disk within the array, SHR divides each hard disk into smaller chunks, creating additional redundant storage. The capacity of each disk can be utilized to the maximum, thus optimizing total volume capacity.

Store Files Quickly:
You do not need to wait for the volume setup to complete before storing data in NAS server. With SHR, you can start moving data into DiskStation during the volume creation.

Reliable Fault Tolerance Mechanism:
Depending on your choice, SHR provides 1 to 2 hard disk fault tolerance of data protection. If one hard disk fails to function properly, your data is still accessible unaffected.

Synology's Virtualization Support
VMware vSphere 5 Support:
When deploying DS3612xs NAS Server, businesses are entitled for:
- Better flexibility to deploy and migrate VMs
- Higher storage performance and storage efficiency with VMFS-5 file system
- Smoother access and management efficiency with load balancing automation in Storage vMotion
Synology NAS servers also support other major virtualization solutions. Synology is dedicated to simplifying virtualized storage management while increasing business agility within large data centers. This dedication extends beyond the support for large-scale businesses. Even budget minded SMBs are able to introduce virtualization into daily operations.

Synology NAS servers run on the same operating system, DiskStation Manager. Therefore, all Synology NAS servers are capable of operating within a virtualized environment.* 5
