(ATS4-PLAT06) Considerations for Sizing and Deployment
Ian Kerman
Support Scientist, Platform Support
The information on the roadmap and future software development efforts are intended to outline general product direction and should not be relied on in making a purchasing decision.
• Considerations for Sizing
• Considerations for Deployment
• Considerations for Virtualization
• CPU
• Memory
• Disk Space
Agenda
First…
• …this is not a session on performance tuning or optimization
• Sessions that cover this topic:
– ATS2-07 (Solving Large Computing Challenges with Pipeline Pilot)
– ATS2-25 (Advanced Planning for Pipeline Pilot Deployments)
– ATS3-PLAT08 (Optimizing Protocol Performance)
– ATS3-PLAT11 (Advanced Planning for AEP Deployments & Migrations)
– ATS4-PLAT03 (Balancing Security with Access for Development)
– ATS4-PLAT08 (Server Pool Management)
– ATS4-PLAT10 (Planning Your Deployment for a 64-bit World)
Considerations for Sizing
• Number of Concurrent Users / scisvr Processes
– Peak vs. Average Usage
• Define Job Types
– CPU, Memory, or I/O Bound
– HPC
• User Performance Expectations
• Plan for future growth
Considerations for Deployment
• Identify your user types
– Web User, Internal User, External User
• Define entry points
– Internal, External Network, Web, CRO

Considerations for Virtualization
• Virtualization is not officially supported, but we are working on it
• If you need to use virtualization…
– Make sure the virtual server is properly sized
– Virtual resources should be “reserved”
– Can be difficult to troubleshoot performance issues
CPU
• 2-4 scisvr Processes per Core – 2 for CPU Bound Jobs
– 4 for I/O Bound Jobs
• AEP performs well with Hyper-Threading
• Benchmarking with the NGS collection has shown better performance with Intel Xeons than with other processors1
• Jobs that benefit the most from CPU investment – Next Gen Sequencing
– Discovery Studio
– High-usage Web Applications

Demo
Memory
• 1 GB per scisvr Process
• Swap space should be 2x amount of memory
• Jobs that benefit the most from Memory investment
– Next Gen Sequencing (Assembly)
– Data Caching Components (Merging, Joining, Sorting, etc)
– Java-heavy Protocols (Reporting)

One More Thing…
• Don’t forget about your network
– Database Servers
– File Servers
– Clusters and Grids
– Local vs. Remote
• Documented server requirements are just a starting point
• Consider number of users, types of jobs
• See the new Deployment Guide in AEP 9.0
