The Thecus W16850 NAS Enclosure grants you access to sixteen storage bays and four Gigabit Ethernet ports to create a storage pool of data for networked systems. The sixteen bays support standard and enterprise-grade HDD and SSDs with a SATA or SAS interface, while a LSI HBA card provides RAID support for increasing the drive's performance and redundancy capabilities. You would need to purchase a license to activate the Windows Storage Server 2016 operating system. To manage the OS, apps, and data, the W16850 is armed with a 3.4 GHz Intel E3-1231 v3 processor along with 16GB of DDR3 ECC memory.

  • Enterprise Capacity Powering Big Data
  • SATA 6G and SAS 12G for Ultra-Fast Transfer Speeds
  • Productivity Enhancing Efficiency with Deduplication and ADS
  • Single-Instance Storage (Dedup)

Other notable connections include four USB 2.0 and two USB 3.0 ports as well as VGA, PS/2, expansion, and RS232 ports. Powering your drives and the W16850's components are done by a redundant 500W power supply. In addition, four hot-swappable fans are on board to cool the internal components and drives.

Software Functions:

Improved Networking

  • BranchCache
    BranchCache can help you optimize Internet usage, improve performance of networked applications, and reduce trac on your wide-area network (WAN).
  • NIC Teaming
    NIC Teaming, also known as load balancing and failover (LBFO), allows multiple network adapters on a computer to be placed into a team for bandwidth aggregation or trac failover to prevent connectivity loss in the event of a network component failure.
  • SMB Multi-channel
    SMB Multichannel enables le servers to use multiple network connections simultaneously. It facilitates aggregation of network bandwidth and network fault tolerance when multiple paths are available between the SMB 3.0 client and the SMB 3.0 server.

Data Access & Protection

  • Work Folders
    A new feature that facilitates the BYOD (bring-your-own-device) scenario by enabling users to access work les from their personal computers and devices. Organizations retain centralized control over their data and can specify device policies such as encryption and lock screen password.
  • DFS Replication
    Enhancements include increases in scalability, the ability to do database cloning and corruption recovery, a Windows PowerShell module, a new WMI provider, faster replication on high bandwidth connections, and recovery tools for conicts.
  • Failover Clustering
    Failover clusters provide high availability and scalability to many server workloads. These include server applications such as Microsoft Exchange Server, Hyper-V, Microsoft SQL Server, and le servers. The server applications can run on physical servers or virtual machines.

Enhanced Scalability

  • Storage Spaces
    Storage Spaces delivers Software Dened Storage (SDS). Easily group multiple hard drives into a storage pool and protect data in the pool, without the need to understand RAID. Storage Spaces enables cost-eective, highly available, scalable, and exible storage solutions for business-critical deployments.
  • Data Deduplication
    Controls data growth by removing duplicate data. Allows the server to eciently store, transfer and backup less data.

Server Virtualization Deployment

  • Hyper-V
    Windows Server Hyper-V oers a scalable and feature-rich virtualization platform that helps organizations of all sizes realize considerable cost savings and operational eciencies. Using Windows Storage Server 2016 Standard, you can take advantage of new hardware technology, while still utilizing the servers you already have.
  • OEM Appliance OOBE (out-of-the-box experience)
    Enhancements include added support for four-node cluster deployments and a wizard for creating a domain controller within a Hyper-V VM that can be used to deploy a turnkey cluster-in-a-box.

Storage Protocols

  • iSCSI Target Server
    Improvements to iSCSI Target Server include support for VHDx (VHD 2.0) virtual hard disks for capacities of up to 64 TB. iSCSI Target Server also now supports SMI-S, enabling end-to-end provisioning using System Center Virtual Machine Manager.
  • SMB
    Improvements to the Server Message Block (SMB) protocol include better SMB Direct performance, automatic rebalancing for Cluster Shared Volumes (CSV) on scale-out le servers, shared VHDx les, Hyper-V Live Migration over SMB, SMB bandwidth management, detailed event messages, and more.
