Virtual Volumes (VVol) is about making the storage system VM-centric, in other words making the VMDK a first class citizen in the storage world. No decision to purchase a product should be made based on this technical preview. The features and their implementation as shown in the lab are subject to change.
Please do complete the pre-flight steps to insure that things are working - this will help insure a smoother experience for you. Reminder: This is a virtualized lab environment running pre-beta software, and therefore performance to be slower than normal - please be patient. There's a CLI reference guide located with the firmware downloads.Lab Overview - HOL-PRT-1467 - Virtual Volumes with Dell EqualLogic Lab Guidance GrpName> vol sel VOLUMENAME thin-growth-warn 100%Īny command at the GUI can be done at the CLI by the way. GrpName> vol sel VOLUMENAME thin-growth-warn ? You can adjust that to 100% to disable the alarm. If you are using thin provisioned volumes, the default warning is 60%. So even if EQL reports 100% full, that does not impact VMware (or any OS) in the slightest. The VMFS knows what blocks are free, and which can be reused. But over time it will again go out of sync. 'esxcli' As long as the volume is not using EQL replication, and the firmware is 6.0+ that utility will bring the in-use space gauge on the volume 'closer' to what the VMware OS reports. VMFS V5+ supports that via a manual utility on the ESXi server. Some newer OS's support a command UNMAP that will tell the storage to return to free space the specified blocks. The array like all block storage only records the writes given it. Do you have plenty of free space in your Datastores? Are you referring to warnings on the array about in-use space exceeding a warning threshold?ĭo not go by what the array GUI shows for in-use space. What version of ESXi and what version of EQL firmware? The screenshots of the errors are not showing up, so I can't help you there.
