What is NFS vaai?
What is NFS vaai?
The NetApp Plug-in for VMware vStorage APIs for Array Integration (VAAI) is a software library that integrates the VMware Virtual Disk Libraries that are installed on the ESXi host. The VMware VAAI package enables the offloading of certain tasks from the physical hosts to the storage array.
What is VMware vaai?
VMware vSphere Storage APIs “ Array Integration (VAAI), also referred to as hardware acceleration or hardware offload APIs, are a set of APIs to enable communication between VMware vSphere ESXi hosts and storage devices.
Does VMware NFS?
VMware supports both NFS version 3 and NFS version 4.1 over TCP/IP. NFS version 3 has been supported since the early days of ESXi. Support for NFS version 4.1 was introduced in vSphere 6.0. There are still some limits to the multipathing and load-balancing approaches that can be taken.
Is vaai enabled?
To determine if VAAI is enabled using the vSphere Client: In the vSphere Client inventory panel, click the host. Click the Configuration tab, then click Advanced Settings under Software. Note: These options are enabled by default.
What is VAAI and VASA?
Both VASA and VAAI belongs to the same family of Storage APIs, used by third-party hardware, software and storage providers to enhance several vSphere features and solutions. The two features work independently, but can coexist. In VMware vSphere 6.0, Virtual Volumes (VVols) introduces a new set of VASA APIs.
How do I know if VAAI is working?
In the vSphere client, select an ESXi host and click on Configuration | Storage Adapters and select your HBA adapter. As you can see in Fig. 1, examine the last column under the heading Hardware Acceleration. If you see “Supported,” that means VAAI is functioning for that particular datastore.
How do I disable vaai?
Disabling VAAI using the vSphere Client:
- Open the VMware vSphere Client.
- In the Inventory pane, select the ESXi/ESX host.
- Click the Configuration tab.
- Under Software, click Advanced Settings.
- Click DataMover.
- Change the DataMover. HardwareAcceleratedMove setting to 0.
- Change the DataMover.
- Click VMFS3.
What is VMware VVOL?
VMware vVols is the low-level storage for virtual machines that supports operations on the storage array level, similarly to traditional LUNs used to create datastores. Instead of using the traditional VMFS file system, a storage array defines how to provide access and organize data for VMs using the storage array.
What is netapp Vasa provider?
VASA Provider for ONTAP uses VMware vSphere APIs for Storage Awareness (VASA) to improve storage management between Virtual Storage Console for VMware vSphere and the vCenter Server. You can use VASA Provider to manage features such as storage capability profiles, alarms, and virtual volumes (VVols).
What two integration features that are provided by a storage array that supports the vSphere storage APIs array integration?
VMware vSphere APIs: Array Integration (VAAI)
- Thin Provisioning Stun.
- Thin Provisioning Space Threshold Warning.
Is NFS safer than SMB?
However, NFS is better with encryption. In the case of random writing, NFS is better than SMB in both plain text and encryption. If you use rsync for file transfer, NFS is a better choice in plain text and encryption.
Is NFS faster than SSH?
For access of large files over the network, NFS is of course much faster than anything with an SSH transport.
What filesystem does ESXi use?
VMFS (Virtual Machine File System) is a clustered file system from VMware that provides storage virtualization. VMFS offers many virtalization-based features, such as: concurrent access to shared storage. Multiple ESXi hosts can read and write to the same storage device at the same time.
How do I disable vaai on ESXi 6?
Note: The below steps need to be applied on all ESXi Hosts connected to the NAS Storage.
- Log into ESXi using SSH/DCUI and execute command: # esxcli software vib remove –-vibname=name.
- Verify that the plugin has been removed using command: esxcli software vib list.
- Reboot the ESXi host to take effect.
What is the difference between VMFS and VVol?
Where VMFS was very LUN-centric and static creating silos within an array, aligning data services to LUNs and utilizing pre-allocated and over-provisioned resources. vVols is VM-centric and dynamic where nothing is pre-allocated, no silos are created and array data services are aligned at the more granular VM-level.
How many VMs is a LUN?
As above, not a single LUN, there isn’t a magic number as depending if you’re using file or block stuff like queue depths and SCSI reservations and other fun stuff can come into it, but rule of thumb 5-6 “heavy IO” VMs and 12-15 light use VMs per LUN is what I do. More than 1 Datastore, and less than 1 per VM.
What is Vasa service?
vSphere APIs for Storage Awareness (VASA) is the VMware-designed API used to communicate between vSphere and the underlying storage, in the case for Pure, the FlashArray.
