  1. SAN, Blade, VM Ware Larry M. Gerlt A+, CNE 3, MCSE 4, CCNA

  2. Overview • SAN and Blades • Advantages • Disadvantage • Who Mosaic chose and Why • VM Ware • Advantages/Uses • Disadvantages/Non-Uses

  3. Advantages - Why Use a SAN • Data Safety • Lost 3 hard drives in one weekend. • Had only one hot spare • Did not lose any data • Disk Space Utilization • Pockets of Space on various Server Raids • Seldom had free space where needed • On a SAN you grow the volume as needed

  4. SAN Disadvantages • Initial Investment • Cost of SAN • Cost of Fiber cards for servers • Cost of Fiber switches • Single Point of failure

  5. SAN Risk Management SPOF • Dual Cisco fiber switches • Dual fiber cards for production servers • Latest iteration – boot from SAN

  6. XioTech Features • Standard SAN features • Redundant Power Supplies • Raid 1, 5, 10 • Central Management • Can define selected disk(s) for • Separate disk space pool • Limiting to specific users

  7. XioTech Features • Unique to XioTech • Change Raid configuration on-the-fly • Upgrade to larger drives one drive at a time • Mix and match drives without having separate pockets of space • Survive multiple simultaneous hard drive failures

  8. Blade Server Advantages • Minimal Rack Space • Reduced power consumption • Ability to reboot “hung” server remotely • Ability to remotely totally down a server and then bring back up. • Central Management console

  9. Blade Server Disadvantages • Initial Investment • We needed to purchase 7 servers to reach a break even point verses buying 1 U servers • Purchasing more servers than fit in one Blade Center • Again face cost deficit unless buying 7 or more servers

  10. IBM Blades • 14 server slots per blade center • Only vender offering quad processor servers when we purchased • Quad proc. Servers require 2 slots • Single or dual fiber port fiber card • Single or dual port NICs • On board CDRom and floppy • Fit in standard Computer Cabinet

  11. Oma LAN COS LAN Mosaic, Omaha CoSentry, Bel. Top Routers - Out to Internet Solid lines = TCP/IP Dashed Lines = Fiber Dotted Line – SAN Repl. via private line San w/backup & Mag Classic server – Oma San with Mag 3D and prod RA data - COS Router Router N/W Switch N/W Switch Pix 515 Firewall Pix 520 Firewall N/W Switch N/W Switch Server Server Fiber Switch Fiber Switch SAN SAN Fiber Switch Fiber Switch N/W Switch N/W Switch

  12. VM Ware Advantages • Server Consolidation • Multiple servers on one • Totally separate virtual server environment for applications that do not “play well with others.” • Reduced overall Hardware costs • DRBC • Can have backup copy of a server • Can drag & drop to other hardware running VM Ware

  13. VM Ware Advantages (2) • Reduced new server build time • Can have a generic server to copy for new servers • Reduced Console requirements • 1 server connected to KB/Mouse/Monitor switch • Multiple servers managed on single server

  14. VM Ware Disadvantages • Initial Hardware Cost • Requires beefed up server • Lots of Ram • More disk space • Dual processor – prefer quad • NIC Overload • Must choose application servers that do not require 100% of NIC (may use second NIC)

  15. VM Ware Disadvantages • Processor overload • Do not recommend for memory and processor intensive applications (SQL or other data base server

  16. Summary • SANs, Blades, & VM Ware: • Improved disk space utilization • Increased DRBC • ROI for hardware $ spent
