Nexsan The Edge

Overview:

• Greater capacity and improved density - up to 84TB
• More robust reliability with Nexsan enterprise class RAID storage
• FC connected RAID storage for higher performance
• Green benefits with Nexsan's energy saving AutoMAID technology
• Consolidates file and block into a single solution with CIFS, NFS and iSCSI

The Edge is designed for businesses that need to consolidate and centralize all their data and storage needs onto a single centralized solution.

The Edge includes fully integrated, Fibre Channel connecting enterprise class Nexsan SAS and/or SATA RAID storage systems. With Nexsan storage, The Edge offers significant advantages over other commodity NAS products. RAID operations are separate and off-loaded from The Edge NAS server maximizing NAS server CPU and memory performance.

The Edge is based on Microsoft WUDSS. Microsoft WUDSS is a dedicated file and storage server technology designed for dependability, seamless integration and delivers the best value in networked storage. WUDSS integrates with existing infrastructures and supports heterogeneous file serving as well as backup of stored data. Its web-based user interface makes management easy and enterprises can make full use of commonly used network environments and standard management software. Nexsan Edge Management GUI – NEM, provides a single interface to WUDSS services and Nexsan storage.

The Edge includes a complete set of data integrity and protection features. Battery backed RAID cache and multiple RAID levels, including hardware RAID 6, ensure data integrity during power outage or double drive failure. Built-in Microsoft snapshots provide data protection of both file and block storage. Microsoft DFS replication protects site data by replicating files to another location.

Energy Saving NAS
The Edge offers the energy saving benefits of Nexsan's revolutionary AutoMAID™ technology. AutoMAID™ (Massive Array of Idle Disks) allows The Edge SASBoy, SATABoy and SATABeast storage units to place its disk drives into several levels energy savings without compromising application performance. This powerful energy saving capability enables users to lower the cost of owning NAS storage.

AutoMAID™ Energy Saving Technology:

Nexsan's evolutionary AutoMAID (Automatic Massive Array of Idle Disks) energy saving technology transparently places disk drives into an idle state to vastly reduce power and cooling costs. AutoMAID delivers the cost-effecdtive benefits of MAID 2.0 without the limitations of slow access times and special host software.

AutoMAID is granular to an individual drive or RAID set and offers multiple levels of energy savings. AutoMAID is user selectable enabling users to determine the right level of response time performance to energy savings. AutoMAID is the first MAID 2.0 architecture that supports VTL, full file format D2D and standard high performance RAID implementations.

Key Points

• AutoMAID reduces power and cooling costs
• Nexsan’s AutoMAID delivers the benefits of MAID without the limitations
• Available on Nexsan Assureon, SATABoy, SATABeast, and SATABeast Xi

AutoMAID Defined

• AutoMAID automatically reduces power consumption and heat generation on idle drives
• Trade-off between response times and power savings are user configurable
• AutoMAID behavior happens automatically and transparently to host – no software changes required
• Typical configuration settings:
  • Level 1: Heads Unloaded
    • 15% to 20% savings
    • Sub-second recovery time
  • Level 2: Heads Unloaded, slows to 4000 RPM
    • 35% to 45% savings
    • 15 second recovery time
  • Level 3: Stops spinning (sleep mode; powered on)
    • 60% to 70% savings
    • 30 to 45 second recovery time

AutoMAID Safety Features

• In maximum power saving mode, drive spin up is sequenced to reduce power surges
• Drives automatically wake up for periodic surface scan to ensure data integrity (user configurable)
• AutoMAID has no impact on performance if left on in data-intensive server applications
• Only two simple configuration settings – "timeout" and "power savings desired"

The Edge GUI - Configuration and Management:

Nexsan Edge Management – NEM™ – provides a unified interface to Microsoft WUDSS management services and Nexsan storage system management. The Edge management system is simple to learn and use and offers a single-pane-of-glass view into your Edge system.

The Edge management system enables administration and monitoring of all WUDDS services and storage for terabytes of capacity and 100’s of volumes. It can be accessed across any LAN, MAN or WAN. The user interface is simple, automated, and intuitive. It greatly reduces the time it takes to perform administrative tasks.

In addition to NEM, the native Microsoft WUDDS management interface and services can be used to administer the entire NAS server. User authentication for The Edge include: Microsoft® Windows Server™ 2003 Active Directory® service, Kerberos, Windows NT Domains, NTLM, and Apple User Account Management (AUM), NIS.

Sample Nexsan Edge Management

Additional access via the RS-232 serial port or network interface to an ANSI terminal or emulator. Event log for all significant events stored on disk. Single click access to summary of all problems and warnings. Arrays are verified before being put into production; automatic "parity scrub" (array verify) is performed as a background task every 24 hours thereafter. Shows status of disk drives, power supplies, fans, RAID controller. Information is automatically refreshed. Complete hardware status page lists all significant hardware conditions such as voltages, temperature, battery mode, cache settings, network settings, and blower RPM Supports automatic IP address assignment via DHCP, manually using a static IP address over serial port, via web page, or by use of the IP Config Tool. Cache management page allows configuration of Cache as enabled or disabled, or remotely settable via standard SCSI commands

Build RAID sets (and set RAID level and stripe size), partition RAID sets into Volumes, map Volumes to LUNs and Host Ports, and manage Spares. For each drive, complete Model Name, Capacity, Serial Number, and Firmware Revision is reported along with errors and retries, if any. Alerts and warnings sent out using SMTP email alerts with problem summary, hyperlink to the enclosure management page, plus user-defined fields. Basic SNMP trap support. Extra security feature requires manual confirmation of destructive media operations. Battery-backed Real Time Clock/Calendar is used to time stamp all major events. Configure and monitor subsystem using most standard web browsers.
