Dell EqualLogic PS4000 Server Storage (iSCSI SAN)

The Dell EqualLogic PS4000 Server Storage is a robust enterprise-class storage array designed to provide centralized, scalable and reliable storage for businesses, data centres, branch offices and virtualization environments. Built around iSCSI (Internet Small Computer System Interface) technology, the PS4000 allows servers to access shared storage over standard Ethernet infrastructure, making it a practical alternative to more specialized Fibre Channel SAN environments.

The PS4000 family was designed with a focus on simplified storage management, data protection and high availability. Depending on the specific PS4000 configuration, the platform supports SATA or SAS drives, with hot-pluggable drive options and redundant components available on supported configurations. Dell documentation lists PS4000E configurations with up to 16 SATA drives and capacities ranging from 4TB to 32TB, depending on the installed drives.

Reliable and Scalable Storage

The Dell EqualLogic PS4000 is particularly suitable for organizations that need centralized storage for file servers, databases, virtualization, backups, business applications and shared enterprise data. Its EqualLogic architecture allows storage resources to be managed as part of a SAN group, while supported configurations can be expanded by adding compatible EqualLogic arrays.

For data protection, supported PS4000 models provide RAID options including RAID 5, RAID 6, RAID 10 and RAID 50, helping organizations balance capacity, performance and redundancy according to their workload requirements.

High Availability & Hot-Swappable Components

For configurations equipped with dual controllers, the PS4000 provides controller redundancy designed to improve storage availability. Dell also specifies hot-swappable disks and redundant power/cooling components on supported models, helping administrators perform maintenance while minimizing service interruptions.

The platform also incorporates battery-backed controller memory for data protection. Dell’s PS4000E documentation specifies up to 72 hours of data protection through battery-backed memory.

iSCSI Connectivity & Easy Management

The PS4000 uses standard Ethernet-based iSCSI connectivity, allowing compatible servers to connect without requiring dedicated Fibre Channel infrastructure. Dell documentation specifies Gigabit Ethernet ports for iSCSI and management connectivity on the PS4000 generation.

Management capabilities include storage provisioning, volume management, monitoring and configuration through EqualLogic management tools. Supported features include snapshots, thin provisioning, storage pools, automatic load balancing and online storage movement, depending on firmware and configuration.
