  • 1. Enterprise file services Module 12 HP Restricted
  • 2. Objectives
      • Identify HP StorageWorks enterprise file services and customer business needs
      • Describe the business value of HP StorageWorks enterprise file services
      • Describe HP StorageWorks enterprise file services features
  • 3. Business challenges
    • Don’t lock me into a proprietary systems— I don’t want to be at the mercy of a single vendor
    • My storage needs are rapidly increasing and I have fewer people to manage it.
    • I want to leverage my investment—people, equipment, processes, etc.
    I think I’m paying too much! Business needs File serving needs
    • Scalability—buy what I need today and let me add when I want to
    • High availability— support for mission-critical environments
    • High-performance NFS file serving needs
    • Industry-standard solutions
  • 4. Qualifying questions
      • What would it mean to you to be able to increase your file service capacity and support large file systems, while maintaining data integrity regardless of hardware failures— all within your current SAN infrastructure?
      • How much would your business profit if your remote offices could consolidate and centralize data in the data center and access that centralized information at LAN-type performance without having to invest in architecture?
  • 5. Enterprise File Services — meeting enterprise business needs Enterprise file services
    • Complete line of HP ProLiant Storage Servers
    • Support for Oracle, SQL Server, Exchange, etc., with iSCSI Feature Pack software
    • Application Storage Manager for radically simple storage management
    • Clustered Gateway
    • Scalability (bandwidth and capacity)
    • Availability (failover with complete data integrity, multipathing)
    • Protocol support (NFS and CIFS)
    • Management and solution stack
    • WAN Accelerator
    • LAN file serving performance over the WAN
    • File and Exchange server consolidation
    • Eliminate backup issues
    Solution capabilities Small and medium business Branch office Enterprise
  • 6. Bringing file serving availability, scalability, and performance to HP storage solutions HP StorageWorks Enterprise File Services Clustered Gateway
    • Availability
      • All nodes monitor health
      • Fully transparent failover—preserve client state information
        • Hardware failover from one failed node to another happens in ~5 seconds
    • Scalability and performance
      • Additional nodes can be added for nearly linear increase in performance
      • Supports up to 16 nodes
      • No forklift upgrades
    • Storage scalability
    • Customer can meet both storage and file serving scalability needs
    • Snapshot integration with EVA storage arrays
    HP Clustered File System
  • 7. HP StorageWorks Enterprise File Services Cluster—optimized scalability & availability Traditional NAS / filer design Multiple paths: No bottleneck Symmetrical cluster file system Bottlenecks: Metadata server and Hot Spots Distributed file system and metadata server designs Clustered File System Design: Built into shared data and shared storage design Requires redundant data, storage, and servers Traditional clustering prone to error, downtime Availability: Performance increases linearly as scaled out Metadata bottlenecks and hot spots can cause problems as they are scaled out Limited — requires distinct file systems for each node. Clustering is for HA not performance Performance: Scales to 16 nodes Scales to many nodes Scales to two nodes Scale-out:
  • 8. Architecture — distributed file systems
    • Each node has a piece of the overall file system
    • Hot spots are a typical problem
    • Requires redundant failover hardware pairs
    Client network Node Node Storage Node Node Storage Node Node Storage Node Node Storage Director Meta Data Node(s) Director Meta Data Node(s) Director Meta Data Node(s)
  • 9. Architecture — symmetrical clustered file systems Client network Node Node
    • Each node sees the complete file system
    • Any node can fail over for any other
      • More efficient use of node hardware
    Node SAN Storage Storage Storage
    • Eliminates hot spot and load balancing issues
    • Distributed Lock Manager – scales with cluster

  • 11. HP StorageWorks Clustered Volume Manager Software (optional)
    • Improve storage utilization across cluster
      • Collapse storage silos into a single higher utilized storage pool
      • 16TB per file system
      • Concatenation or striping of LUNs
    • Optimize for price:performance.
      • Use many cost-effective arrays/LUNs instead of single expensive array
      • Stripe across many arrays/LUNs for best performance
    • Flexibly manage storage across your business
      • On-line volume growth
      • Single shared pool of data to provision, manage, and backup
    • Group
    • Stripe
    • Expand online
    Cluster file system Shared Volume Physical storage devices
  • 12. HP StorageWorks Enterprise File Services (EFS) WAN Accelerator
      • IT appliances built on HP ProLiant platforms
      • Deployed in remote site and data center
      • Accelerates CIFS, NFS, HTTP, FTP, MAPI
      • Transparent to clients and servers (in-band or out-of-band)
      • Failthough capability for in-band
      • Utilizes:
        • Caching
        • Best-in-class compression
        • Latency optimization
        • Predictive traffic analysis
      • Replaces need for replicating data sets around the network and enables consolidation to central site
      • EFS WAN Accelerator Manager to configure and monitor all nodes across enterprise

  • 13. EFS WAN Accelerator value proposition
    • Potentially new virtualized datacenter infrastructure
    • Potentially new thin client architecture
    • NAS
    • WAN appliance running file cache in branch offices
    • C&I
    • Managed services
    Solution components
    • Provides enterprise CIOs with a significantly higher degree of control over infrastructure assets
    • Higher degree of centralization and control over information assets to more easily comply with Sarbanes-Oxley
    • Estimated 30–40% reduction in TCO from:
      • Server/storage/client consolidation and resource optimization
      • Reduced labor intensive support/maintenance costs
      • Decreased facilities costs
    Value proposition Large enterprises (>10,000 employees) with a high percentage of workforce distribution across branch office and field office structure (for example, global financial services, retail, healthcare, services companies) Target customers
