NEXSAN NST4000 UNIFIED STORAGE WITH FIBRE OPTION  

If you prefer Fibre Channel to other SAN protocols, this scalable storage is built for you. The Nexsan NST4000 by Imation expands the availability of fault-tolerant FASTier™ DRAM caching and Fibre Channel SAN connectivity, and puts them in reach of mid-range businesses

Hybrid Storage  is defined as a combination of solid-state disk (SSD) and hard disk drives (HDD) in a single storage system.

Use SSD to increase the cache memory pool so that I/Os are accelerated before they go through the controller to the back-end disk drives. The larger the cache memory pool, the greater the likelihood of getting a cache hit without having to access the back-end disks—which results in greater application performance.

A fully unified, enterprise-class, unified hybrid storage solution that simultaneously supports block and file traffic eliminating the need for organizations to invest in separate SAN and NAS storage systems.

The introduction of NST4000 and NestOS 3.1 brings our NST6000 fault tolerant FASTier DRAM caching and Fibre Channel SAN connectivity features to the mid-range. The addition of Fibre Channel to NST4000 expands NST’s availability for those organizations that need a mid-range storage system but prefer Fibre Channel over other SAN protocols. Fibre Channel adds to NST’s unified storage capability that already includes 10Gb and 1Gb Ethernet for NAS and iSCSI connectivity. NST’s NAS includes support for CIFS/SMB, NFS and FTP.

Scalability – NST4000 offers non-disruptive scaling options that allow you to scale up to 2.1PB in capacity and to scale performance with FASTier™ and offloaded RAID processing. This level of flexibility enables businesses to right size their initial acquisition and grow as application performance or capacity requirements change.

[restab title=”Key Features”]

• Performance Agility:
  Compared with traditional caching techniques, cost effective FASTier™ technology accelerates performance for mixed application workload environments.
• Unified Flexibility:
  Provides a mix of CIFS, NFS and FTP file sharing protocols for enterprise NAS file sharing as well as iSCSI and Fibre Channel SAN block storage protocols for server volume sharing, with inline data compression that shrinks capacity requirements and improves performance.
• Hybrid Scalability:
  Scalable storage with options that let you right-size capacity up to 2.1PB and fine-tune performance with FASTier and RAID offload to meet your business’s changing needs.

EFFICIENT:

FASTier™ – Intelligent, self-tuning hybrid caching capability that uses a scalable pool of cache memory comprised of both high speed memory and flash technologies to create a more efficient hybrid storage solution. DRAM and Flash SSD technology is used to accelerate read and write IOPS and throughput. FASTier works transparently so there is no administration burden to turbo-charge I/O performance and handle the constant growth of mixed applications in your environment. FASTier is especially useful for random I/O workloads such as databases or for VMware, Xen or Hyper-V environments.

Unified Storage with Inline Data Compression – In a single solution, NST4000 provides CIFS, NFS and FTP file sharing protocols for enterprise NAS file sharing as well as iSCSI and Fibre Channel SAN block storage protocols for server volume sharing. Inline data compression reduces the amount of data written to SSD or HDD media reducing total capacity requirements and datacenter footprint and improves storage system performance. As data is written, NST compresses data, file or block, prior to it being written to the RAID volume. This reduces the amount of data written to SSD or HDD media, and in-turn shrinks the total storage capacity requirements, datacenter footprint and improves storage system performance. NST Inline Compression can be set on a per volume basis and is a transparent operation.

AutoMAID® Power Management – In NST4000, each RAID set can have its drives progressed into deeper power saving levels when they have not been accessed for a specified period of time, saving up to 85% in power in the disk array. AutoMAID Power Management is transparent to applications.

FLEXIBLE:

Three-Dimensional Scaling – NST4000 offers scales capacity and performance across three dimensions with each dimension carrying its own level of flexibility.

• Capacity is scaled by adding additional NST storage modules. NST storage modules come in different form factors to address different organizational needs. NST storage modules choices include 18, 32, 48 and 60 drive high-density storage form factors. Storage capacity can be comprised of solid state drives or hard disk drives.
• Storage Processing is scaled with each new NST storage module head. Each NST storage module head has its own RAID and I/O processing capabilities offloading this work from the NST controllers. As you add NST storage module heads, you are adding more RAID and I/O processing.
• FASTier™ – Caching is NST’s intelligent, self-tuning hybrid caching capability that uses a scalable pool of cache memory comprised of both high speed memory and flash technologies to create a more efficient hybrid storage solution. FASTier provides increased performance for mixed application workload environments over traditional caching techniques.

Unified – In a single solution, NST4000 provides CIFS, NFS and FTP file sharing protocols for enterprise NAS file sharing as well as the iSCSI SAN block storage protocol for server volume sharing.

AVAILABLE:

High Availability – NST4000 includes redundant controllers, data paths, storage module controllers and power supplies to keep your applications and users productive. User selected RAID protection levels include 10, 5 and 6. Cache protection options ensure that your data is safe even if the power goes out.

Business Continuity –

• Synchronous Replication – Want to increase your application system availability a step further? NST offers another level of data availability within the system with synchronous mirroring between RAID volumes located across storage modules. With synchronous mirroring your applications run continuously even in the event of an entire storage module or its expansion were to fail.
• Asynchronous Replication – NST4000 also provides the ability for you to replicate your most mission and business critical data to another system across an IP network that is geographically dispersed making your data available to you in the event you need to recover from a site disaster.
