How busy is our site? Avg. 132,000 web sessions/day Avg. 900,000 page views/day Avg. 122.5 MM database transactions/day Avg. 907 GB of data read/written/day
How busy is our site? - continued Anticipating a 40% increase during
Holiday Avg. 185,000 sessions/day Peak of 262,000 sessions 1.9 MM page views in a single day Avg. 171 MM database transactions/day Avg. 1.2 TB of data read/written/day
High-Level Architecture – Before
Dedicated server solution for IIS and SQL. Not enough SAN space for all servers,
most SQL servers utilized slower DAS. Equates to a lack of flexibility, reduced
scalability, and greater licensing and rack costs.
High-Level Architecture - Now Virtualized/blade server environment.
14 blade servers, 3 rack mount servers, 25 VM’s
High speed SAN storage available for all servers, with SQL utilizing EFD’s.
Scalability achieved with less cost and greater speed.
Virtualization reduces licensing costs and hardware costs.
Business Drivers for Colo Change Cost of rack space Cost of bandwidth On-site support MetroE connectivity to Charlottesville
