The Dell EqualLogic^™ PS4000 Series of virtualized iSCSI SAN arrays are designed to bring enterprise-class features, intelligence, automation and reliability to remote or branch office, departmental and small-to-medium business (SMB) storage deployments.

The PS4000 Series addresses branch office and SMB storage needs with simplified administration, rapid deployment and an affordable price, while providing a full set of enterprise-class data protection and management features, solid performance, scalability and fault-tolerance. With 10,000 RPM SAS disk drives, the PS4000X array provides up to 9.6 TB of storage for a great balance of cost-effective performance and capacity. To grow storage capacity and performance for remote office needs, two PS4000 arrays can be combined in a SAN group. To further scale out the SAN, EqualLogic PS6000 arrays can be added seamlessly without sacrificing the initial investment in PS4000 arrays.

To help prevent both under-utilization and over-provisioning, EqualLogic PS Series arrays are based on a virtualized modular storage architecture that enables IT managers to purchase only the storage they need, when they need it. Using innovative data movement technology, all EqualLogic PS Series arrays within a SAN work together to automatically manage data, load balance across all resources, and expand to meet growing storage needs.

Offering built-in storage features previously available only to top-tier data centers, the PS4000X enables best-practice storage for remote, branch-office and departmental deployments. The EqualLogic PS Series arrays include the following enterprise data services and software features with no additional software licensing fees: SAN HeadQuarters Multi-SAN Historical Performance Monitoring, Auto-Replication, RAID Load Balancing, Complete SAN Virtualization, RAID Load Balancing, Storage Pools, Thin Provisioning and much more.

Speed of Response Options
Dell ProSupport Mission Critical
Servers and storage are the backbone of your infrastructure. Every minute of unplanned downtime is lost productivity and quite often, lost revenue. Reducing recovery time from days to hours is a must. It’s for these scenarios that Dell offers the Mission Critical Option, Dell’s most rapid response option. With this option, you can choose from 2-, 4-, or 8-hour onsite response service for rapid resolution and reply on Dell’s demonstrated Critical Situation (CritSit) Process to get you back up and running fast.

Data Protection Options
Keep your Hard Drive
Enables you to maintain control over your sensitive data by retaining your hard drive while it is covered by your limited hardware warranty.

Proactive Options
Dell ProSupport for IT with Enterprise-Wide Contract
Dell believes that support should be more than break-fix—it’s about preventing problems before they happen. Offered with Dell ProSupport for IT, the Enterprise-Wide Contract option provides a deep support relationship and is ideally suited for more complex IT environments. Includes a designated Service Delivery Manager, performance benchmarking reporting, proactive planning, and custom reporting to help you maximize uptime and performance— and, ultimately, reduce costs.
