  • The architects of the Dell EqualLogic PS Series rethought storage from the ground up, taking smart principles from elsewhere in the computing world and applying them to the product. Virtualization, IP networking, and page-based data movement are a few examples. Beyond technology design, also rethought the business principles that made buying, expanding and improving traditional shared storage difficult and painful. The result is a storage experience that impresses product reviewers and award judges, but more importantly empowers and delights customers.
  • Best practices: Mix RAID levels among members within a pool with different drive speedsMonitor available capacity closelyUse SAN HQ to plan, monitor and analyze
  • With the PS4000 Launch: The same software features included. However, the capabilities are optimized to satisfy the needs of remote office and small medium businessesWith this launch we have added some software functionality, but we have kept the same no cost model that is standard for EqualLogic.A few features to highlight that where launch with the PS6000 Series: -With FW 4.1 (Highland Park), we have added RAID 6 support on all arrays (PS6000/PS6500) and added additional RAID support on the PS6500E (5 and 10) -Added Hyper-v support to ASM/ME -Added SAN HeadQuarters (multi-SAN management and performance monitoring)Existing EqualLogic customers can download these software items and update their arrays to use the new features.
  • Key PointsThe PS6000/6010XVS delivers exceptional performance for multi-tiered workloadsThe PS6000/6010XVS is an outstanding primary/active storage option for virtual desktop workloadsEqualLogic PS6000XVS/PS6010XVS Intuitive data availability for multi-tiered applications PS6000XVS/PS6010XVS Features: Sixteen drive array providing intelligent placement of data across SAS and SSD drives to deliver exponential data response time. Each array automatically tiers data based on analysis of previous IO patterns Each array combines 8-450GB, 15,000 RPM SAS and 8-100GB, SSD SATA drives for a total of 16 drives and 4.4TB of storage capacity per array
  • Storage tiering can enable significant savings and improve application performanceIdentify your goals for tiered storage; set quantitative targets and time framesEqualLogic PS Series virtualized iSCSI SANs offer simplified tiering design, implementation and managementDell’s suite of IDM products and services can help shore up success
