Windows VM Migration Prerequisites On the source hypervisor, power off all the VMs that you want to migrate. Ensure that the source VMs do not have any hypervisor snapshots associated with them. (Optional) Clone any VMs that you want to preserve. (Optional) Create a storage container on the AHV cluster. (For ESXi source environments) Windows…
Supported Source Environments You can migrate VMs from the following source hypervisors to AHV: VMware ESXi Microsoft Hyper-V Unified Extensible Firmware Interface (UEFI) Support Information In the current AOS and AHV releases, the UEFI implementation is limited. The following table describes the level of support available for various usage scenarios: Scenario Support Level Generation 2…
Compression Select the check box to enable compression. A Delay (In Minutes) field appears after checking the box. Enter a zero to enable inline compression or a value (number of minutes) to enable post-write compression, which can begin (up to) that number of minutes after the initial write. All data in the storage container is…
Snapshots + Clones DSF provides native support (VAAI, ODX, etc) Leverage redirect-on-write algorithm VM data consists of files (vmdk/vhdx) which are vDisks Snapshot taken = vDisk marked immutable New vDisk created as read/write Both vDisks have same block map Metadata mapping to corresponding extents Since each vDisk is its own block map, it eliminates need…
Erasure Coding Similar to RAID where parity is calculated, EC encodes a strip of data blocks on different nodes to calculate parity In event of failure, parity used to calculate missing data blocks (decoding) Data block is an extent group, and each block is on a different node belonging to a different vDisk Configurable based…
A storage container is a defined subset of available storage within a storage pool. Storage Containers allow you to apply rules or transformations such as compression to a data set. Logical segmentation of SP containing groups of VM’s/files (vDisks). Typically have 1:1 mapping with datastore VMware Storage presented via NFS (default) or iSCSI AHV Storage…
The Health dashboard displays dynamically updated health information about VMs, hosts, and disks in the cluster. To view the Health dashboard, select Health from the pull-down list on the left of the main menu. Screen Details The Health dashboard is divided into three columns: The left column displays tabs for each entity type (VMs, hosts, disks, storage…
Configuring Alert Emails Prism Central allows you to configure the alert messages sent by Prism Central. To configure alert settings, reporting rules, and message templates, do the following: Configuring Alert Policies The system monitors a variety of conditions and sends an alert whenever one of the alert conditions is detected (when alerting is enabled). There…
