适用场景

适用于VMware vSphere (OTV) 9.12及更高版本的ONTAP工具

问题描述

调整内存设置: 
  • Virtual Storage Console (VSC)、VASA Provider (VP)和Storage Replication Adapter (SRA)虚拟设备在VM (OVA)中运行、并对其许多进程使用Java。
  • 在大规模环境中、可以通过增加Java堆内存设置来提高性能。
  • 在某些情况下、NetApp支持部门可能也会建议其他客户调整这些设置。特定进程内存不足可能会影响用户界面和其他应用程序任务的性能。
  • 本文面向9.12及更高版本、这些版本为 大规模环境中的Java堆内存设置增加了更精细的粒度。
什么是大规模?
  • NetApp工程部建议将这些阈值作为可能从这些调整中受益的大规模环境的指标。
  • vSphere或ESXi主机数量:25个或更多
  • 数据存储库数量:50个或更多
  • LUN数量(传统数据存储库LUN以及VVOLProtocol Endpoint LUX*):100或更多
  • NFS挂载数量(FlexVol卷):100或更多
*作为VVOL数据 存储库的每个FlexVol卷都有一个PE LUN。
