vFabric Elastic Memory for Java (EM4J) is designed for customers running virtualized Java applications on vSphere. Focused primarily on memory management and performance analysis, EM4J gives you the insight and power to get the most efficiency and performance out of your virtualized Java applications.
EM4J greatly simplifies the most common configuration and management tasks, such as how to appropriately size virtual machines (VMs) running Java, how to gauge the real memory efficiency of your Java processes over time and how to avoid potential performance problems with configuration alerts.
EM4J also gives you the power to drive further memory efficiencies into your Java workloads by allowing the hypervisor to transparently reclaim memory directly from relatively idle Java Virtual Machines (JVMs), putting them where they are needed most in your virtual infrastructure.
