Adds a Unified Storage Solution for PowerVault™ MD iSCSI storage systems

The PowerVault™ NX3500 utilizes Dell™ Fluid File System and the MD backend for Internet SCSI (iSCSI), common internet file system (CIFS) and network file system (NFS) access to block and file data, enabling a single file share to scale up to the capacity of the MD deployment, currently 389TB* of usable capacity.

  • Powerful: Consolidate block and file data with high-availability unified storage
  • Flexible: Easily add or modify iSCSI-, NFS- and CIFS-based storage as needs grow
  • Secure: Built-in data protection features such as snapshots and replication help provide security and data integrity
  • Certified VMware compatibility: Tested and certified to be compatible with VMware® ESX release 5.0, 4.1 and 4.0
