Dell PowerVault NX3500 Unified Storage Solution
Adds a Unified Storage Solution for PowerVault MD iSCSI storage systems

Key Benefits:

High performance NAS for the PowerVault MD platform

The PowerVault NX3500 works with PowerVault MD32x0i and MD36x0i storage arrays to help provide affordable unified storage with iSCSI, CIFS and NFS access to block and file data. If you need to manage an ever-increasing amount of unstructured (file) data, this easy-to-use solution is ideal. The PowerVault NX3500 can give you more flexibility than traditional unified storage because it has no architectural limits to file-system size. You can scale a single share to the full capacity of your PowerVault MD deployment.

The PowerVault NX3500 incorporates the high performance, highly optimized Dell Fluid File System and offers affordable data protection features. When combined with a PowerVault MD iSCSI array, it gives you the flexibility and cost of ownership advantages of unified storage.

Pay-as-you-grow scalability

There's an avalanche of unstructured data headed your way. File intensive user shares, rich content and virtual environments demand ever-increasing amounts of storage. But now you can avoid the costs and headaches of continually adding-and having to manage-more file storage systems.

A flexible and practical alternative to Windows file servers

Managing multiple file servers and namespaces can consume your resources. The PowerVault NX3500 lets you consolidate so you can store more data and manage it more easily. It uses Dell Fluid File System to optimize file-access performance and hardware utilization, and eliminates the capacity constraints typical of file systems.

The PowerVault NX3500 features an easy, wizard-based NAS configuration utility for initial setup. A web-based user interface, NAS Manager, conveniently enables you to configure NAS storage, create and modify volumes and shares, and monitor performance. The PowerVault NX3500 NAS Manager also lets you set up alerts, snapshots and replication, and supports NDMP backup.

Dell Fluid File System

Dell Fluid File System is a distributed file system that presents a storage pool as a single file system with a single IP address to the client(s). It uses cache efficiently to provide fast, highly reliable reads and writes and optimizes file access performance and hardware utilization. Dell Scalable File System also incorporates volume management, cluster management for transparent fail-over, and non-disruptive scalability.

Affordable data protection

The PowerVault NX3500 also includes user-restorable snapshots and replication. You can use these built-in features to protect both new and existing file shares.

Highly available hardware

With its dual active-active file controllers and backup power supply, the PowerVault NX3500 gives you data protection and excellent performance with no single point of failure.
