This feature is an NFS persistent storage plugin. Previously only iSCSI storage devices could be used to provide persistent storage in Abiquo. For more information about persistent storage in Abiquo see Manage External Storage
The main aim of this feature is to bypass the iSCSI LUN limit in ESXi. Customers using a persistent disk model with previous versions of Abiquo could not scale their offering because they could not sell more than 256 persistent system disks or volumes in an ESX cluster. This feature overcomes this limitation through a transparent integration with no changes to GUI screens, API calls or use cases. This feature also enables customers to use any storage device with NFS support for persistent storage, whereas previously managed storage devices could only be iSCSI devices.
NFS persistent storage is not available on Hyper-V
Previously you could only set a storage allocation method for the whole Abiquo platform. Now you can configure a storage allocation method for each storage tier in a datacenter.
Select NFS storage technology. Enter the IP address and port of the device in Management and Service fields.
In Abiquo 2.6, you can add a storage device more than once using the same IP address because the same device may use more than one storage protocol, e.g.: a NetApp system may contain vFilers and NFS shares
All valid NFS shares on the storage device will be listed as storage pools.
Select an NFS share (pool) and assign it to a tier.
You can now control the usable percentage of the storage pool and the maximum number of volumes that will be created in it.
In Abiquo 2.6 GA, the abiquo.storagemanager.storageMethod property has been removed. The platform default is Progressive. If you wish to change the default, set a value for each tier you wish to change in every datacenter. Note that this property is deprecated in Abiquo 2.6 Preview.
Set the storage allocation method for the tier:
NFS shares are folders on a shared disk. Abiquo 2.6. does not control the space used across multiple folders, so the best practice is to add only ONE shared folder per device.
NFS shares are included in the list of datastores on hosts (as disabled) but Abiquo will not protect them. This means that a Cloud Admin could enable one of them as a hypervisor datastore for Abiquo to deploy standard VMs on. For this reason, Cloud Admins must be aware of the designated use of each storage device and datastore to ensure NFS disks used for persistent VMs are not used as datastores for non-persistent VMs too.
Abiquo will not allow you to add the datacenter's NFS Repository as a storage pool via the GUI or API.
As for all external storage, Abiquo supports VM movements but not volume movements.
