In Development - targeted for an upcoming release
- Striping of volumes across multiple physical NVMe drives, in order to enable larger volume capacity and enhanced single drive performance to more than 1 Million IOPs.
- Revisions of supported hardware are planned, in order to accommodate faster NIC performance.
- Multi-LUN aggregation support (creating super LUNs, consisting of many smaller LUNs that can span physical NVMe drives for increased capacity).
- Physical NVMe drive hotplug removal/addition.
- SIM enhancements towards added VM actions.
- Advanced recipe marketplace management with easier UI components.
Compatibility and Limits Matrix
Please visit the following link for further information on compatibility and limits: Compatibility and Limits Matrix for version 3.0.0
- In order for the GPU device to be assigned to a different VM, the persistence mode should be disabled. For more information, please refer to the section "Disable NVIDIA GPU Persistence mode" in the following document: Disable NVIDIA GPU Persistence mode
- Occasional connection issues to PV guest console. Suggested mitigation solution is to reboot the VM.
- The automated installation of PV drivers for MS Windows ISO images is not currently supported. An end-to-end functional solution is currently in the development process.
- Editing an existing VLAN network is not currently supported. In order to edit the VLAN, you must delete and recreate the network.
- It is not possible to edit the network configuration of a VM in the case the instance boots from an CD/ISO.
- For a VM instance that is booted from CD/ISO, Sunlight does not initialize the cloud init logic. Network configuration must be applied on the VM by the user.
- The maximum supported virtual disk size which is currently tested in the system is up to 2TB. Larger size vdisk deployments are currently under test.
- Simultaneous resizing of multiple VM instances is not currently supported.
- During the upgrade phase, master and slave nodes will be required to be booted down. Currently, the upgrade is performed manually by the Sunlight support team.
- It is recommended that the maximum number of instances created in a cluster (all at once) should be limited to less or equal than 8.
- Please use “SHIFT”, instead of the “CAPS LOCK” button, for capital letters, when typing the login/password of an instance through the VNC console. Using the “CAPS LOCK” button currently results in misspelled username/password.
- Instances that will be moved and/or backed up in the SIM dashboard should have only one root disk. The existence of extra disks is currently not supported in this case.
- The "Create snapshot" action currently does not support massive parallelism. We are currently testing to lift the limitations.
- There is a caveat in using all physical NICs on an AWS cluster. Physical NICs 0,2,3 should be used only for private networks. Physical NIC 1 should not be used at all. The rest of the physical NICs, 4 to 15 should be used only for public access networks. In future releases this will be handled automatically via the virtupian UI.
