Virtualization use cases addressed by Veritas InfoScale products
Veritas InfoScale product components support the following virtualization environment use cases:
Table: Virtualization use cases addressed by Veritas InfoScale Solutions in a Linux environment
Virtualization use case | Recommended Veritas InfoScale products | Virtualization technology supported | Implementation details |
|---|---|---|---|
Server consolidation | SFHA or SFCFSHA in the guest | Red Hat Enterprise Linux (RHEL) KVM SUSE Linux Enterprise Server (SLES) KVM RHEV Linux on Microsoft Hyper-V | How to run virtual machines as physical servers. See Server consolidation. |
Physical to virtual migration | SF in the host SFHA or SFCFSHA | RHEL KVM SLES KVM RHEV | How to migrate data from physical to virtual environments safely and easily. |
Simplified management | SFHA or SFCFSHA in the host | RHEL KVM SLES KVM RHEV | How to manage virtual machines using the same command set, storage namespace, and environment as in a non-virtual environment. |
Application failover | VCS or SFHA in the guest | RHEL KVM Red Hat Enterprise Virtualization (RHEV) SLES KVM Linux on VMware ESXi Linux on Microsoft Hyper-V | How to manage application monitoring on virtual machines. How to manage application failover on virtual machines. See Cluster Server In a KVM Environment Architecture Summary. |
Virtual-to-virtual (in-guest) clustering | VCS in the guest | RHEL KVM RHEV SLES KVM Linux on Microsoft Hyper-V Linux on VMware ESXi Oracle Virtual Machine (OVM) | How to configure VCS for virtual-to-virtual clustering. See Installing and configuring Cluster Server with Microsoft Hyper-V virtual-to-virtual clustering. |
Virtual machine availability | VCS in the host | RHEL KVM RHEV SLES KVM | How to manage virtual machine failover. See VCS in host monitoring the Virtual Machine as a resource. |
Virtual machine Live Migration | SFCFSHA in the host | RHEL KVM SLES KVM RHEV | How to use features such as instant snapshots to contain boot images and manage them from a central location in the host. How to enable use of SSDs or HDDs by leveraging Flexible Shared Storage (FSS). FSS value proposition: Storage provisioning offered by Veritas InfoScale Solutions in the host that would allow storage to be provisioned to virtual machines from a single pool having the same namespace across machines in a hypervisor cluster. The cluster need not have shared storage as local storage can be shared using the FSS option. See About live migration. |
Virtual machine Live Migration | SFCFSHA in the host | RHEV | How to use features such as instant snapshots to contain boot images and manage them from a central location in the host. See About live migration. |
