Stick around for SWAG! (Prize drawing at 5.00 p.m)  All our volunteers and organisers do not get paid for running SPS SQLSaturday Cambridge and do it because they believe in the power of community (or are just plain nuts). Please show your gratitude for making this possible by:  Giving them a hug  Shaking their hand  Saying thank you  Coming back next year  Consider getting your company to pay for a precon next year  Speading the word  Getting involved yourself  But most of all, by enjoying the day!  Don’t forget to thank the sponsors for their support  Thank the speakers for donating their time, energy and expenses

 WHAT did we try?  Classic Setup  SAN Read-Only  A read-only LUN can be shared between multiple servers, and hence enables you to use more than query server on the same physical disk.  Dedicated Processing Architecture  WHAT did we NOT do?  Client Load Balancing – Every Client Connects to a Specific Target Query Server  Query/Processing Flipping Architecture  Say What one more Time…

Ref:

 Initial requirement was to add redundnacy to SPOF  Improved initial active / passive setup to active / active  Better use of hardware  Scale-out enabled  Two possible solutions  Hardware load bancing (F5)  Software load balancing (ASLB)

 Opted for software load balancing  Based on ASLB from Microsoft (SQL CAT team). Open source.  Pros  Flexibility. Configuration per solution.  Control. Software load balancing based on metadata.  We can build a configuration interface – and we have  Cons  Known issue with PerformancePoint where we see intermittent errors. Have not troubleshooted this yet.  Complex kerberos delegation paths  HTTP connector. Some overhead when moving large amounts of data

 Web front-ends  Connection strings point here.  E.g.  Web front-ends are actually load balanced, but only for redundancy (active / passive)  Analysis Services  Each instance has the HTTP connector configured  Meta data  Web front-end checks meta data and HTTP redirects user  Round robin and observing”enabled / disabled” (server or database), server avail and CPU load  SQL Agent jobs validate server availability and CPU load and updates meta tables

 Deploy new database  Done by updating the meta data in the ASLB database  When a new entry has been added to dbo.Databases  >

 Enable / disable a database  Done from SharePoint web interface.
