15. Good Things Clustering Table partitioning Faster builds Easier growth Caching speed PhotoSource http://www.flickr.com/photos/pcka/3240903696/
16. Not-So-Good Things Black box Cachingmay not help Compatibility lists More drivers Tough to grow SAN adminsmay not help Photo Source http://www.flickr.com/photos/stewf/95709873/
18. “We’ll keep an eye on it for ya.” Perfmon changes Neighbors change SAN changes SAN monitoring software is tough Photo Source http://www.flickr.com/photos/mrjoro/39470992/
19. What’s Your Bottleneck? Not Enough Drives Drives Too Slow Shared Drives RAID Level SAN Controllers Partition Alignment Drivers Multipathing
20. Things to Monitor Hard drives Controllers (CPU, caching) Controller connectivity to the network Network switch throughput Server connectivity to the SAN (the HBA) Server drivers
21. The X Factor: Redundancy Hard drives – hundreds Controllers – 2+ Controller connectivity to network – 4+ Network – separate networks, switches Server connectivity to SAN – 2+ Network fabrics – iSCSI, Fiber, WAN
22. SAN Monitoring Strict HCLs, SCLs Cross-platformmeans JAVA No “full” picture Very, very, veryexpensive Photo Source: http://flickr.com/photos/earthandeden/865393933/
24. Start From The Beginning Get block sizes right Align partitions Design for pathing Test with SQLIO Install SQL Server Monitor sec/read, write Save history
43. Working Around It Data/logs/tempdbon different volumes Separategroups of DBs Separate DBinto filegroups TempDB, backups Photo Source http://www.flickr.com/photos/doodlemonger/2667917978/
44. Wrapping It Up Test before deployment Learn multipathing Design DB files around SAN limits Monitor forever Get vendor help Photo Source http://www.flickr.com/photos/doodlemonger/2667917978/
