PS Series - Intelligent, Enterprise-Class Storage
Founded on the premise of simplifying networked storage, EqualLogic's PS Series is a family of intelligent, iSCSI-based storage arrays that fundamentally change storage economics from purchase and set up to operation and upgrades. All configurations are completely interoperable and upgradeable - performance and capacity scale without disrupting application or data availability.

Enterprise Reliability- Each PS Series array offers fully-redundant, hot-swappable components including controllers, fan trays, and power supplies. Support for RAID 5, 10 and 50, hot drive sparing, automatic failover and rebuild, and patent-pending proactive media error detection deliver 99.999% data availability - or, 5 minutes of planned downtime per year.

Enterprise Performance - Starting with 300 MB/sec and 60,000 IOPS and scaling to more than a million IOPS, the PS Series delivers unmatched performance in its class. Automatic load balancing seamlessly moves data across all active RAID sets, maximizing performance by intelligently optimizing network connections, cache, and controllers in real time.

Enterprise Data Services - The PS Series comes standard with a comprehensive set of software features including virtual volume management and space-efficient snapshots for instant backup and restore, volume cloning for rapid server provisioning, Auto-Replication, multi-path I/O support, and cluster support for comprehensive disaster recovery.

Choose the PS Series array that fits your requirements today with the confidence that you can scale to meet future needs - without a forklift upgrade or application downtime!

EqualLogic PS Series Architecture - EqualLogic Solutions deliver the benefits of consolidated networked storage in a self-managing, iSCSI storage area network that is affordable and easy to use, regardless of scale. By eliminating complex tasks and enabling fast and flexible storage provisioning, EqualLogic solutions dramatically reduce the costs of storage acquisition and ongoing operations.

Patented page-based volume management enables automatic movement of data while it is in use. This technology provides the foundation for online expansion, automatic configuration and load balancing, performance optimization, and advanced software functionalities – all with continuous access to data. That means no downtime for increasing capacity, moving data between storage tiers, or load balancing storage, and most management tasks are handled by the array, not the administrator. As a result, EqualLogic makes enterprise-class shared-block storage practical for all servers and applications.

Unique Peer Storage Architecture - With EqualLogic’s patented peer storage architecture, “peer” means collaboration and equal partnership in a single, simple architecture where components and arrays work together to share resources, distribute loads, and collaborate for maximum performance, total data protection, and seamless scaling. This architecture enables the array to perform numerous functions that eliminate complexity. These include:

• Peer deployment, which enables PS Series arrays to be fully functioning 20 minutes after opening the box.
  
• Peer control, which enables the array to continuously monitor resources and automatically manage configuration, load-balancing, capacity expansion, storage pools and tiers, volume snapshots, and replication.
  
• Peer provisioning, for online, on-demand capacity expansion without disruption, including dynamic allocation of disk space, connectivity, security, and performance for every application.
  
• Peer protection, which delivers comprehensive system monitoring, proactive disk drive scanning, group event notifications, multipathing, instant recovery, and disaster protection.
