Dell EqualLogic PS5500E  Storage Array Overview

The PS5500E is an intelligent storage array that is designed to provide rapid installation, simple management, and seamless expansion. All PS Series storage arrays include SAN configuration features and capabilities that sense network topology, automatically build RAID sets, and conduct system health checks to help ensure that all components are fully functional. A PS5500E is designed to be installed, configured, and serving storage in less than one hour.

Dell 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 — helping to prevent both underutilization and over-provisioning. Using innovative data movement technology, all Dell EqualLogic PS Series arrays in a SAN work together to automatically manage data, load balance across all resources, and expand to meet growing storage needs.

The Dell EqualLogic PS5500E  Series is designed to meet and exceed the rugged requirements of the data center. The PS5500E includes fault tolerance capabilities through fully redundant and hot-swappable components — standard dual-controllers, dual fan trays, dual power supplies, and disk drives with hot spares.

Dell EqualLogic PS5500E  Series arrays represent a breakthrough in storage economics, from purchase and setup to operation and upgrades. Unlike traditional SANs, the PS Series comes complete with the available software and applications expected from an enterprise-level SAN. The PS5500E Series scales on-demand — and online — allowing storage growth without disrupting applications. As a result, Dell EqualLogic PS5500E arrays provide exceptional flexibility at a low total cost of ownership.

Whether consolidating a direct-attached storage (DAS) infrastructure, migrating data from an existing SAN, streamlining data protection processes, or simply adding storage capacity, the Dell EqualLogic PS Series offers a family of proven, high-performance, self-managing storage arrays designed to meet the requirements of any SAN environment.

Dell EqualLogic PS5500E Controller Redundancy

The EqualLogic PS5500E can be configured with either a single controller, or dual redundant controllers. The single controller configuration will provide the same level of I/O performance as a dual controller configuration. The dual controller configuration provides for redundancy. Redundant controllers will prevent volume connections between hosts and SAN from being dropped in the event of an active controller failure.

The Active Controller is the controller which is processing all disk and network I/O operations for the array. A second controller in dual controller configurations will always be in a “passive” operating mode. In this mode, the secondary controller will exhibit the following characteristics:

• Each of its Ethernet ports are electrically inactive (active lights are off)
• The passive controller cache mirrors the cache of the active controller

Dell EqualLogic PS5500E Controller Failover

To support redundant controller fail over, each Ethernet port on the active controller that is connected to the EqualLogic PS5500E SAN must have its corresponding port on the passive controller also connected to the same SAN network. In the event of a controller failure, the passive controller will immediately activate and continue to process all data requests to the array. The following changes occur during fail over:

• The backup controller automatically enables each of the corresponding Ethernet ports that were enabled on the failed primary controller
• The IP addresses that were assigned to each of the failed controller Ethernet ports are reassigned to the corresponding ports on the second controller

A link failure on one or more of the Ethernet ports on the active controller does not constitute a controller failure. For this reason, it is important to ensure that ports from each controller are connected to at least two different switches. This will prevent a switch failure from also disabling all paths between a host and its connected volumes.
