Agenda • To Grid or Not To Grid • The Approach • The Metrics • Lessons Learned • Looking Forward
To Grid or Not to Grid: The Problem The Heterogeneous SAS Environment • Multiple versions of SAS • Multiple servers with multiple OS versions • Multiple data stores and multiple types • Shrinking resource pools • Shrinking budgets • A new service provider This is not unique to SAS… it is everywhere!
Why SAS Grid? • One standard for HC and PHAC. • Local data storage. • Limited data traffic across WAN/LAN. • Dramatic increase in performance. • Reduced licensing cost (Single contract). • Reduced Single points of failure. • Complete solution for Analytics/Reporting. • Scalability, Reproducibility and Flexibility. • Security, Auditing and Monitoring
Levelling The Playing Field What Really Happens Just Kidding !
The Approach Infrastructure • Leverage Existing Hardware Investments • HP BLc7000 Blade Enclosures • HP Proliant BL460c G6 Blades • HP EVA 8000 SAN • Promote to Production Environment • HP BLc7000 Blade Enclosures • HP Proliant BL460c G7 Blades • 3PAR T800 Storage System
The Approach The Security Flow LDAP Server METADATA server SAMBA Server Grid Nodes SAS User Mid-Tier Desktop
The Approach The Security Layers Corporate LDAP SAMBA Server METADATA server Nodes SAS User Mid-Tier Desktop • Department Wide • Centrally Managed • Linux file system ACLs • LDAP and Metadata are “synced” • UID and GID are unique • Linux ALCs use exact GIDs and UIDs • Unique UID • Membership in • groups • Corporate • Security • Policies
The Metrics: The Best of Both Thanks to Tom Kari for providing his test scripts
The Metrics: Teky Stuff Technology Choices: Hardware • HP BLc7000 Enclosure • Easily scalable – 16 device bays • In house expertise • Server/Storage/Back-up in same data centre • Keep data traffic off Corporate Ethernet Back-bone • HP Proliant BL460c G7 Blade • 2x Intel Xeon 2.66 GHz (8 cores) • 100 Gb DDR3 Memory (Max 384 Gb) • 2x 8 Gb Fiber Chanel HBAs (Host Bus Adapter) • 2x 10Gb Ethernet Adapters • 2x 300Gb Internal Drives
The Metrics: Teky Stuff Technology Choices: Hardware Continued • 3PAR T800 • 40 TB of disk space (Expandable to 800 TB Raw) • Capable of offering 3-tiered storage • SSD • FC • SATA • Has been recently discontinued by HP • CommVault Back-Up solution • Existing solution
The Metrics: Teky Stuff The View from Behind Courtesy of HP: www.hp.com
The Metrics: Teky Stuff Technology Choices: Software • OS - SuSeLinux Version 11 • Base image identical for all servers • Simple to image new server • Additional packages required • Metadata server • Application server • Mid-Tier server • SAMBA server (Data access) • Grid nodes are all identical
The Metrics: Teky Stuff Technology Choices: Software • Software Specifics • OCFS2 clustering software • All Servers can mount • SAS binary and configuration • User home directories • Data directories • SAS GRIDWORK
The Metrics: Teky Stuff Technology Choices: Software • Software Specifics • Multipath technology • Provides 4 paths for each server to 3PAR storage
The Metrics: Teky Stuff Technology Choices: Configuration • A few specifics • Grid Master is “Closed” • 2 Queues created “Normal” and “Priority”
Lesson’s Learned • The core issue • Bandwidth, Bandwidth, Bandwidth… • Isolate Data Traffic • Avoid data movement across corporate Ethernet backbone • Encourage “local” data access • User engagement • Critical to bring the end user into the process from the start • Understand how SAS is being used. The end state • Change is not easily adopted.
Lesson’s Learned • The Linux vs Windows issue • Legacy issues continue to be a concern • Use of SAS PC File Server foreign to some • Phased approach to user migration • Enable small groups vs entire organization at once • Provide a mechanism for user feedback/problems • Provide detailed documents –That nobody reads • Monitor the SAS Grid proactively • Identify key difficulties for clients • Login, data access, data sharing, desktop configurations, library and coding standards • Contact clients before the issues drives them nuts.
Forward Looking • Collaboration • Several Federal Department and Agencies are engaged and committed to the Grid technologies • We have the ability to define the road map ahead • What works best • Talk and exchange successes (and issues) and map them to your own business needs • Resist the silo • Facilitate change • We no longer live in isolation,
Forward Looking • The BIG DATA vision
