  • Page 2: Executive Summary

    This document provides specific details about the configuration and bill of materials for one such Fast Track 4.0 reference architecture, based on the HP ProLiant DL980 G7 server using HP P2000 G3 MSA storage. This configuration is targeted at a data warehouse or data mart environment with scan rate requirements of around 11-17GB/sec.

A complete SQL Server DBMS (Database Management System) configuration, or “stack," is a collection of all the components that are configured to work together to support the database application.

  • Page 4: Solution Criteria

    HP currently supports both Fast Track 3.0 and, Fast Track 4.0 (SQL Server 2012). The configurations with external storage leverage the HP P2000 G3 MSA FC Dual Controller SFF array, which allows for dual reads when drives are mirrored. For sequential data reads from data warehouse queries, this capability enables tremendous throughput per storage volume.

  • Page 6 More information regarding the Fast Track Data Warehouse reference architecture approach, including the means of calculating building blocks for other HP server and storage combinations, is included in the Microsoft SQL Server Technical Article, “Fast Track Data Warehouse Reference Guide for SQL Server 2012”.

  • Page 7: Capacity Summary

    Technical white paper | HP ProLiant DL980 G7 and P2000 G3 MSA Storage Capacity summary Several data capacities are cited in this document, including Maximum Data Capacity, and Fast Track Rated Database Capacity. The following summarizes these values: Maximum Data Capacity: This is raw data space minus the required minimum space for TempDB database files, multiplied by the Fast Track compression factor (3.5).

  • Page 8: Database Configuration

    Technical white paper | HP ProLiant DL980 G7 and P2000 G3 MSA Storage Database configuration The testing for this DL980 G7 solution was performed using a 6.5 TB test database and a workload simulation program. The performance numbers depicted in this document are output from the simulation tool running both a simple and complex workload.

  • Page 9: Queue Depth Settings

    Queue Depth settings Several tests were run to determine the optimal Queue Depth settings using the HP 82E Host Bus Adapters (HBAs). All tests performed for this reference configuration used a Queue Depth setting of 64. Testing found optimal Queue Depth settings ranging from 48 to 64.

    Technical white paper | HP ProLiant DL980 G7 and P2000 G3 MSA Storage Note: In other architectures with 4 LUNs per array, we only have to have 1 map per LUN. Now with 2 LUNs per array we MUST have 2 maps per LUN to maintain performance.

  • Page 16: Manual Storage Mapping

    Technical white paper | HP ProLiant DL980 G7 and P2000 G3 MSA Storage Manual storage mapping All Fast Track architectures require a Microsoft Multipath I/O (MPIO) manual mapping scheme. This manual mapping scheme uses the “Fail over Only” MPIO policy for SAN connected storage. Each LUN has a primary and one or more secondary maps.

  • Page 19: Disaster Recovery

    Through the use of the HP P2000 VSS (Microsoft Volume Shadow Copy Service) Provider for Windows x64, the Fast Track server can be “paused” while a snapshot is taken, then resumed once it is complete. This allows the databases that are contained within the snapshot to be in a consistent state for the replication process.

  • Page 23: Implementing A Proof-Of-Concept

    Technical white paper | HP ProLiant DL980 G7 and P2000 G3 MSA Storage Implementing a proof-of-concept As a matter of best practice for all deployments, HP recommends implementing a proof-of-concept using a test environment that matches as closely as possible the planned production environment. In this way, appropriate performance and scalability characterizations can be obtained.
