ENTERPRISE-CLASS FEATURE SET
NAS (CIFS and NFS) Services
Shared Folders can be accessed through CIFS, NFS or both. FTP services are also provided.
iSCSI Block Services
iSCSI volumes can be provided to physical or virtual servers for direct-attached or SAN connections.
DRAM & 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. FASTier is especially useful for random I/O workloads such as databases or for VMware, Xen or Hyper-V environments.
Online Capacity Expansion
Add additional hard drives to any storage pool to increase its capacity on the fly without impacting active clients. I/O will automatically be balanced across all drives by the NST5000.
There is no performance penalty for taking snapshots. Up to 2048 snapshots are supported. Storage does not need to be reserved to hold snapshot data. The management GUI makes it easy to setup and manage snapshot creation and deletion schedules. Snapshots are mountable for testing or other purposes. Granularity is per pool, per share, or LUN.
Asynchronous replication is WAN efficient because it only transmits delta blocks to the destination side. All snapshots taken on the source side are available on the destination side for backups, data mining or testing purposes. Granularity of replication is a storage pool, a share, or a LUN.
Synchronous replication places two Nexsan E-Series storage systems under the Nexsan NST5000 head, each connected via Fibre Channel. Writes are acknowledged after they are simultaneously placed onto both E-Series, so they are always identical. Together with failover/failback support, synchronous replication provides the utmost in business continuity.
Quotas / Thin Provisioning
More storage can be allocated than actually exists in the system – referred to as oversubscription. Alarms warn of limits reached, so storage can be added.
IEEE 802.3ad link aggregation allows multiple Ethernet ports to be combined for faster throughput.
Data Protection Suite
Provides Nexsan NST5000 with snapshot and replication capabilities.
Performance Enhancement Packages
Increase the memory to 48GB per controllerand add a second Xeon multi-core processor in a Nexsan NST5300 or increase the memory in the NST5500 to 96GB per controlle.
ENTERPRISE-CLASS PERFORMANCE AND RELIABILITY
The Nexsan NST5100 utilizes SSD, SAS 15K RPM or NL-SAS 7200 RPM drives to meet varying storage needs. The Nexsan NST5300 and NST5500 models store their data on Nexsan E-Series disk arrays, which support mixing and matching SSD, SAS 15K RPM and SATA drives.
Drive Stress Tests
Stringent drive stress tests ensure that only the best quality drives go into Nexsan storage systems.
System Drive Tests
Drives are tested in the storage system prior to being shipped to a customer, to ensure top quality and ongoing reliability, then removed and packaged for shipment.
State-of-the-art anti-vibration dampening maximizes reliability and performance in the high density Nexsan E-Series disk arrays that are utilized by the Nexsan NST5300 and NST5500.
Cool Drive Technology™
Push/pull fans modules and specially designed air channels optimize drive cooling and reliability of the high density Nexsan E-Series disk arrays that are utilized by the Nexsan NST5300 and NST5500.
Dual Storage Controllers
Dual controllers provide a no single point-of-failure solution. Should one controller fail, the second will perform all of the I/O operations as well as utilize its I/O ports for connection to external storage.
RAID 5/6/10 are provided to protect against a single drive failure or two drives failing at the same time.
All active components are redundant and hot-swappable including power supplies, disks and controllers.
Nexsan E5500 and E5300 Controller I/O Ports
Each Nexsan NST5300 or NST5500 storage controller provides (2) to (6) 1Gb Ethernet ports, (2) optional 10Gb Ethernet ports; as well as (2) to (6) 8Gb Fibre Channel ports for connection to the E-Series disk arrays.
Nexsan E5100 Controller I/O Ports
Each Nexsan NST5100 storage controller provides (2) to (6) 1Gb Ethernet ports, (2) optional 10Gb Ethernet ports, as well as a 24Gb SASx4 port to the NST5100X expansion chassis
POWER AND SPACE EFFICIENCY
Industry-leading Storage Density
The Nexsan NST5100 delivers up to 32 drives in 6U of rack space, providing an industry-standard 5 drives per U of storage density.
The Nexsan NST5300 delivers up to 240 drives in 19U of rack space, while the NST5500 delivers up to 360 drives in 27U, providing an industry-leading 13 drives per U of storage density.
AutoMAID® Power Management
In the Nexsan NST5300 and NST5500, 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. No changes need to be made to applications to get the advantages of AutoMAID.
EASY TO MANAGE
Quick Start wizard
Get the storage system up and running in 15 minutes or less.
Easy to Manage
A revolutionary GUI design makes it easy to set-up, manage and monitor the storage system. Wizards guide the IT generalist through setup, share and LUN creation and management, snapshots, volume management, replication, clustering, user management and security, and setting up alerts.
A Web server residing in the storage system presents the management GUI in a Web browser. Administer storage systems remotely. There is no need to install management software on a client computer and keep it updated. Use Windows Computer Manager to manage Share/Folder/File permissions for users and groups as well as LUNs.
Single Pane-of-Glass Management
Remotely manage one or many systems. Nexsan storage systems find each other, and appear in the management console, which displays their health using red/yellow/green indicators. Easily move between systems to administer them.
Automatic RAID Set Maintenance
In the event of a drive failure, spare drives are automatically added to a RAID set and a RAID set rebuild is run – all without any manual intervention being required.
Alerts are sent via SNMP or email and are stored in system log files. They are transmitted to the Web browser-based management console.
Network Time Protocol client relieves the administrator from having to set, adjust and synchronize clocks across systems.
Backup with popular backup and restore solutions through the industry-standard NDMP V4 interface or backup LUNs using any popular backup and restore applications. NDMP V4 preserves all access rights for CIFS and NFS shares, and uses background snapshots for fast backups.
Storage system administrator can grant limited rights administrators per storage pools. These administrators can create, manage and delete shares and LUNs, perform snapshots and replication, and manage share-level access permissions.
Data Migration Tools
Helps to move data between storage systems.
Active Drawer Technology™
Active drawers hold the drives to enable easy, hot-swappable management of extreme density without heavy lifting or having to power down the Nexsan NST5300 or NST5500 storage system. On the Nexsan NST5100, the drives are front-accessible.
