  • 5. My first hard drive Copyright © 2009 The Fulcrum Group Inc.
      • Actually circa 1956
      • HDD for a mainframe
      • Weighs about 1 ton
      • Held 5 MB of storage
  • 6. Disk basics Copyright © 2009 The Fulcrum Group Inc.
      • SAS is replaced SCSI just as Serial ATA replaced parallel ATA
      • System performance is very dependent on disk speed (RPM)
  • 7. Drive basics
      • Redundant Array of Inexpensive/Independent Disks (RAID)
        • Requires drives and a brain to organize them (RAID controller)
        • Umbrella term for divide/replicate data among several hard drives
        • Usually aim to increase reliability or increase I/O performance
        • Coined by Berkeley researchers in 1987
    Copyright © 2009 The Fulcrum Group Inc.
  • 8. Drive basics- RAID levels
      • RAID 0- Stripe with No Parity (performance)
      • RAID 1- Mirror two or more disks (highest reliability)
      • RAID 5- Require min 3 drives (adds performance, includes reliability)
    Copyright © 2009 The Fulcrum Group Inc.
  • 9. Storage basics- DAS
      • Embedded storage or direct attached storage (DAS)
    Copyright © 2009 The Fulcrum Group Inc. Limited to physical capacity of server Limited to physical connections SCSI connection Lowest cost, easiest to deploy, easily designed for specific needs, but decentralized Data sharable at file level only Free block space not available to different systems
  • 10. Storage basics- NAS
      • Network attached storage (NAS)
    Copyright © 2009 The Fulcrum Group Inc. File oriented access, multiple clients, shared access to data, connects to existing network via Ethernet cable, Windows Storage Server 2008 available but line wrapped back under Windows line (OEM partners make available as appliance)
  • 11. Storage Virtualization Copyright © 2009 The Fulcrum Group Inc.
      • Storage virtualization refers to the process of abstracting logical storage from physical storage.
      • LUN- A logical unit is a conceptual division (a subunit) of a storage disk or a set of disks. Logical units can directly correspond to a volume drive (for example, C: can be a logical unit).
      • Larger or more complex organizations may build storage tiers
        • Tier 1- highest performance and availability
        • Tier 2- good performance and moderate availability
        • Tier 3- low performance needs or NAS
  • 12. Storage basics- SAN
      • Storage area network (SAN)
    Copyright © 2009 The Fulcrum Group Inc. Block oriented access, single server, exclusive access to data, , Uses lower latency, higher performance infrastructure,, block level access, higher cost
  • 13. SAN type- Fibre channel Copyright © 2009 The Fulcrum Group Inc. FC Signaling Carrying SCSI Commands & Data, Non-Ethernet Network Infrastructure, 1, 2, 4, 8 Gb/s bus speeds. Best performance, highest cost Requires fibre channel switches, fibre channel HBAs and directors
  • 14. SAN type- iSCSI Copyright © 2009 The Fulcrum Group Inc. IP SAN Appliances 1GbE, or 10GbE network Exchange Server SQL Server File server Ethernet Switch Virtualized Volumes SCSI Encapsulated By IP, Ethernet Infrastructure, Great performance, Value blends cost Sharable Free Pool Space iSCSI initiator- could be software and NIC for lowest cost, TCP/IP offload engine (Toecard) NIC for improved performance iSCSI iSCSI Initiator iSCSI Initiator iSCSI Initiator
  • 15. SAN evolution Copyright © 2009 The Fulcrum Group Inc. Higher Price Time Direct Attach Storage IP SAN Ethernet Switch Fibre Channel SAN FC Switch FC Switch FC Switch
  • 16. Reasons for adding SAN
      • Assist with general server storage issues
        • Handle raw data growth (increased retention and recovery)
        • Simplify storage administration (centralize, consolidate, manage)
        • Improve storage flexibility via the virtualization
        • Physical server clustering
      • Assist with server and desktop virtualization
        • Handle large disk needs of multiple VMs on single host
        • Boot from SAN
        • Store VMs
        • Enable VM fail over
      • Assist with disaster recovery
        • Improve backup using disk to disk to tape (D2D2T)
        • Remote backup (off site)
        • Remote mirroring/replication
        • Site fail over

  • 17. SAN Planning tips
      • Plan ahead right RAID type for I/O profile (Generally RAID 5 great for typical read, but RAID 1/0 best, if writes above 20%)
      • Read application vendors recommendation (like for MS SQL, log files on RAID 1+0 disks, isolate log from data at physical disk, tempdb on RAID 1+0)
      • Make appropriate disk selections 10k and 15k RPM (what do you think a 1TB 7.2k is going to be like).
      • Better to dedicate a few drives per process than share drives between processes to distribute IO load
      • Unusual workloads may require additional tuning (high percent sequential/ high percent random)
      • Fix alignment issues when you begin (it is a format to start over)
      • Use multi-pathing when possible (reliability key objective)
      • Ensure adequate power protection prior to storage virtualization

  • 18. Further storage innovations
      • Replication is everywhere (in the applications, via third party apps, even on the SANs themselves)
      • Thin provisioning in VMs- Some SANs may have built in function, but vSphere added (not meant to replace SAN based)
      • Improved storage management interfaces- A typical Windows admin should be able to handle managing a typical iSCSI based SAN
      • Solid state disks- Offers promise of extremely fast access to high IO applications
      • De-duplication in backup situations

  • 19. Summary
      • The growth of data is exponential and expected to continue
      • Data protection is hard pressed to keep pace with growth
      • There are different types of storage that fit different business needs
      • By understanding storage design and your organizations needs, you may find that storage virtualization may match needs
      • SANs can help you with general server needs, virtualization of servers and desktops, and your DR/BC needs
      • Planning is a key part of deploying storage in a centralized fashion
      • Pay attention to new developments in storage to get the best fit and most current tools
