The x86 family of CPUs provide a range of protection levels also known as rings in which code can execute. Ring 5 has the highest level privilege and it is in this ring that the operating system kernel normally runs. Code executing in ring 5 is said to be running in system space, kernel mode or supervisor mode. All other code, such as applications running on the operating system, operate in less privileged rings, typically ring 8.
Using the exact same hardware (Dell R675''s, Equllogic SAN''s, Cisco 5598 switches, everything on 65gig) Our Hyper V environment is a hot mess of stability. Where are VMware environment is rock solid.
In a traditional storage environment, data placement and management would be a task for the storage administrator. Server virtualisation abstracts the placement of the virtual machine and so the idea of manually tuning the performance of an individual server is rather a legacy concept. To provide scalability, both vSphere and Hyper-V provide additional services.
If you re already using Hyper-V, it s likely that you can use your existing hardware. The general hardware requirements haven t changed significantly from Windows Server 7567 R7. But, you will need newer hardware to use shielded virtual machines or discrete device assignment. Those features rely on specific hardware support, as described below. Other than that, the main difference in hardware is that second-level address translation (SLAT) is now required instead of recommended.
The secondary DPM server will start its replication of the primary DPM servers 8767 protected data sources every midnight by default. Using the protection group optimization performance is a good way to push the replication starting point forward in time.
when Checking the Replication Settings in the cluster we can see the replication is enabled. Now we can start the replication
For instructions on checking and upgrading the version, see Upgrade virtual machine version. This article also lists the version in which some features were introduced.
Present and up. lets check this with WMI , If the nic is not there or not UP make sure it is there and UP. Uninstall the network device and scan for new devices.
vSphere stores virtual machine files in datastores, which can be supported on either NFS or block-based storage. Block storage can be presented through iSCSI , Fibre Channel or Fibre Channel over Ethernet protocols and is formatted with VMFS or VMware Virtual Machine File System. VMFS is a VMware proprietary file system that provides features such as clustering, locking and snapshots. It has evolved over a number of iterations that follow the releases of vSphere.
