  • 1. SAN PRESENTATION
    Your data uptime is our business
    Author: PHAM HONG PHUOC
  • 2. TERM Definition
  • 3.
  • 4. SAN versus DAS
    • SANs eliminate the topology and distance limitations imposed by traditional DAS solutions
    • 5. SANs support non-disruptive provisioning of storage resources
    • 6. SANs allow multiple servers to easily share access to a storage array orframe
    • 7. SANs provide better infrastructure for multi-pathing
    • 8. SANs enable consolidation of storage peripherals
    • 9. SANs vastly increase scalability, as a net result of the above advantages

  • 14. IBM System Storage DS3400 Summary_ 4 GbpsFibre Channel (FC) interface technology_ Direct-attach storage (DAS) or SAN solution —start with a DAS configuration and seamlessly transition to a FC SAN when ready _ Combination of 12 SAS or SATA 3.5" drives per enclosure _ DS3000 products are geared towards Small and Medium Business (SMB) and departmental environments, SAS and iSCSI attachment technologies are supported as well._ Expandable by attaching up to three EXP3000s for a total of 21.6 TB of storage capacity with 450 GB SAS or up to 48.0 TB with 1.0 TB SATA _2 U rack mount enclosure with 12 easily accessible drive bays _ Management software IBM System Storage DS3000 Storage Manager _ Supported drives Supports 3Gbps SAS 73 GB, 146 GB, 300 GB, and 450 GB SAS drives at 15,000 rpm speeds and SATA disks at 7,200 rpm speed _ Cache per controller512 MB battery-backed cache with 1 GB upgrade option
  • 15. EMC CX3-40s System Storage Summary
    _CX3 series is midrange storage array market in performance and scalability.
    _The CX3-40 and CX3-40c offer an excellent combination of performance and scalability and are well suited for OLTP and messaging workloads.
    _ Storage Processor Enclosures (SPE) offer four Xeon® processors, 8GB memory, and four 4Gb Fibre Channel host connections. The CX3-40c also includes eight iSCSI ports for connection to hosts via Ethernet.
    _ Both models support directly connected hosts or up to 128 HA (dual-connected) SAN connected hosts. And, each array supports up to 240 disk drives for a maximum raw capacity of up to 119TB

    Single View of the Storage Environment
    Management and Reporting is Complex
    • Single view of end to end storage environment
    • 40. Standardize reporting and management tools
    • 41. Manage more capacity per resource, and focus on other IT issues
    • 42. Management is complex and time consuming
    • 43. Configuration data is incomplete, inaccurate & uncorrelated
    • 44. Requires different process and tools for each vendor
  • Introduce VINADATA’s SAN Diagram

    • Common Types of RAID Protection in Storage
    • 50. Common Types Hard Disk
    • 51. Common Types Connection
    _ Level 0: Striped Disk Array without Fault Tolerance. Also known as JBOD
    _ Level 1: Mirroring and Duplexing. Most commonly used for DB and applications.
    _ Level 3: Bit-Interleaved Parity. Used mostly for “streaming” data like audio and video
    _ Level 5: Block Interleaved Distributed Parity. Most used RAID level for balanced
    performance and cost.
    _ Level 6: Independent Data Disks with Double Parity. Provides block-level striping
    with parity data distributed across all disks.
    _ Level 0-1 : Mirror of Stripes
    _ Level 1-0: A Stripe of Mirrors
    FC:
    146GB – 10K Rpm  Price: $1600
    146GB – 15K Rpm  Price: $1955
    SATA II:
    500GB – 7200Rpm  Price: $2065
    FC SAN
    iSCSI SAN (IP SAN)
    Performance of iSCSI SAN = ½ performance FC SAN (depend on connection speed as much)
  • 52. Deliverables for customers
  • 53.
    • Hosting Server and Store Data on SAN
    • 54. Backup on SAN
    _ Clone
    _ Snapshot
    • Backup with Tape Library
    _ Backup Disk to Tape
    _ Backup Disk to Disk
    _ Backup online Database (Database don’t need off line for backup)
    • Disaster Recovery (Service OR/AND Data)
    Combine with ESX VMWare Technologies, we can provide the virtual Server. Assign the Private LUN and the third party software can synchronize data via ADSL, lease line …
    We can build cluster system with server at customer sites and Virtual Server at VINADATA Site if customer‘s want DR both data and service (Such as: Exchange server, SQL Server, Oracle Server …)
