Synchronous Replication Synchronous Replication (SyncRep) maintains two identical copies of a volume across two different storage pools in the same PS Series group for real-time data protection ensuring that a viable, hardware-independent copy of the volume is always available.
Snapshot Space Borrowing The Snapshot Space Borrowing feature enables you to temporarily increase the available snapshot space for a volume by borrowing from the snapshot reserve of other volumes and pool free space, preventing additional overhead costs to deal with temporary usage spikes and allowing you to keep your older snapshots from being automatically deleted.
Volume Unmap Volume Unmap helps recover unused space previously allocated to volumes, offering cost-effective storage capacity utilization for users running VMware, Microsoft, and Linux platforms.
Volume Undelete Volume Undelete enables you to restore volumes deleted by mistake. Deleted volumes are stored in a volume recovery bin, where they are preserved for up to one week, or until free space is required—protecting your data availability.
Support for SED drives and IPsec EqualLogic Firmware now offers support for for SED (Self-encrypting drives) and IPsec—offering you latest in data security.
Data Center Bridging Data Center Bridging (DCB) is designed to improve quality of service with consistent and even traffic flow in a converged SAN/LAN networking fabric.
Automatic Load Balancing EqualLogic load-balancing features automatically balance workloads by seamlessly spreading data across multiple active storage resources, helping maximize performance by intelligently optimizing the available network connections, cache, controllers, and drives.
Peer Storage Architecture "Peer" describes the collaboration and equal partnership of a single, simple architecture. Arrays function as peers and work together to share resources including cache, disks, network and I/O. This cooperation enables the even distribution of workloads, application performance optimization and comprehensive data protection.
Rapid Provisioning The intelligence of virtual storage provisioning combined with the modular design of EqualLogic storage arrays enable you to quickly and easily expand storage capacity without affecting data availability. You can start with a single storage array—then, as storage, performance, and network requirements grow, add more members to help increase capacity, performance, and network bandwidth.
Storage Pools Storage pooling provides the ability, within a single SAN, to create sub-groups of arrays that enable you to optimally configure and prioritize applications for the required level of service. You can configure separate storage pools within a single SAN to help build an efficient, flexible, easy-to-manage storage environment.
Point-in-time Replication EqualLogic point-in-time replication remotely replicates data from one PS group to another over a standard IP network over long distances, helping provide your organization with high levels of data protection and disaster tolerance. |
