ONTAP 9

问题解答

基准测试可能适用的原因
  • 设置新系统
  • 与客户团队一起执行概念验证测试
基准测试可能不合适的原因
  • 基准测试需要调整并发性等参数、以实现最佳性能
  • 基准测试使用的系统性能参数可能与生产工作负载不同
  • 生产工作负载很难精确地重新创建、合成工作负载即使是同一工作负载也可能不会遇到问题
  • 基准可能并不代表生产工作负载一旦放置在新系统上后将要执行的操作
  • 由于以下原因、生产系统中的综合基准性能测试与全新系统的性能不同:
    • 文件系统使用期限
    • 碎片化
    • 数据的有机增长在每个操作中所需的处理量都略为增加、并且性能可以累积
    • 其他工作负载可能正在运行、而新系统可能未运行其他工作负载
