  • 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

  • Other trends driving tiered storage
  • Traditional SAN designs bring limited benefits
    Storage objects are bound to physical resources
    Statically configured and operated
    Individual islands of storage within the SAN
    Performance and capacity resources not easily reallocated
    Difficult and costly to operate
    Specialized training and staff
    Many planned outages for upgrades and migrations
    Professional services often required
    Just to get a configuration operating
    To implement changes
    Enterprise features require additional software licenses
    High acquisition and software support costs
    Costs continue to increase as the environment grows

  • Automation tools on EqualLogic PS Series SANs simplify tiering design and management
    Tier by…
    Disk Medium
    RAID Policy
    Data Protection Treatment
    Organizational Structure
    Other Criteria
  • EqualLogic PS Series SANs support 3 techniques for tiering storage
    Auto-Tiering (via Automatic Load Balancing)
    RAID Preference Configuration
    Pool-Based Tiering
  • Terminology review
    Thin Provisioning
    SAN HQ
  • Challenge #1: A mix of applications and an overworked staff
    Suggestion: Use PS Series automatic tiering
    • Leverages PS Series Auto-Load Balancing algorithms
    • Fully automated mechanism
    Ethernet Switch Fabric
  • Challenge #2: Certain applications in the data center with special storage needs
    Suggestion: Configure PS Series RAID Preference
    Uses Group Manager Advanced volume settings
    Requires multiple RAID policies within a single pool
    RAID preference policy will attempt to honor setting
  • 19
    Challenge #3: Multiple independent user groups that need dedicated storage
    Suggestion: Use PS Series pooling
    Pooling mechanism commits arrays to applications or user groups
    Similar to RAID preference, but policy is enforced, not simply prioritized
    Ethernet Switch Fabric
  • One simple scheme for leveraging PS Series pool-based auto-tiering
  • Define tiers using PS Series featuresall-inclusive with no additional costs
    • Instant on ‘set-up’ manager
    • Group manager
    • Rapid provisioning
    • Roles-based management
    Data Protection and Availability
    • RAID 5, 6, 10, and 50
    • Automatic RAID placement
    • Multi-path / IO support
    • Phone home
    • Enclosure monitoring system
    • Performance monitoring
    Storage Virtualization
    • Complete SAN virtualization
    • Thin provisioning
    • Auto-load balancing
    • Automatic storage pools & tiering
    • Array evacuation
    Data Protection and Recovery
    • Writeable snapshots
    • Multi-volume snapshots
    • Instant restore / cloning
    • Multi-way replication for disaster recovery
    Multi-Group Monitoring
    • SAN HeadQuarters (SAN HQ) event & performance monitoring
    Server Management Integration
    • VSS and VDS Providers
    • Automatic MPIO Connection Management
    • Auto-Snapshot Manager/ Microsoft Edition
    • Exchange , SQL Server and Windows file systems data, now including MSCS

    • ASM/VE 2.0
    • VMware vSphere 4.0 Advanced MPIO integration
    • VMware SRM Storage Adapter
    • Automated DR for thevirtual data center
  • 22
    Challenge #4: VDI stores include both “hot” and “cool” data
    SSD Speed & HDD Capacity
    Suggestion: Use PS6000XVS/6010XVS “hybrid” arrays
    PS6000XVS/6010XVS combines SSD and 15K RPM SAS on a single array
    Automated data tiering hot data within volumes placed on SSD
    Improves performance of multi-tiered workloads like virtual desktops
    Reduces time to boot multiple VMs by up to 76%†
    †Based on testing performed by Dell Labs in May 2010 comparing Dell EqualLogic Firmware v. 4.3 to Dell EqualLogic Firmware v. 5.0 with VMware API for Array Integration. Actual performance will vary based on configuration, usage and manufacturing variability.
