![]() 5 If you want to use Parallels Access from a second computer, go to and sign in to your Parallels account. Make sure that the virtual machine is shut down (Actions > Shut Down). IntelliMagic Vision for z/OS provides recommendations on the number of aliases required for both HyperPAV and Dynamic PAV configurations. Parallels Access Agent for Mac no longer requires kernel extensions to transfer sound between a Mac and mobile device. On your phone or tablet, download and install Parallels Access from the App Store or Google Play Store. I even use Parallels Access on tablets which runs 3D as a native app on any. How many are needed depends mostly on the activity of the volume, where larger volumes (“3390 Model 54”) are more likely to show a high I/O rate. You do need to know how many aliases to assign to each volume. When HyperPAV cannot be used, dynamic PAV (shown in the image) is the preferred option to use, as it will automate the alias management. This mechanism is by far the most efficient. With HyperPAV the alias assignment occurs for each individual I/O request for each LPAR accessing the Disk Subsystem.z/OS will assign the aliases where they are most useful to reduce queuing and to help meet the service objectives of your installation. With Dynamic PAVs the alias assignment will be more dynamic, you simply assign a pool of addresses to each LCU.With Static PAVs the alias assignment is fixed, so you need to manually assign a certain number of aliases to each volume for which you want to reduce queueing.Two different modes are supported in z/OS: The ‘alias’ addresses need to be configured by the installation. PAV uses ‘alias’ addresses are used to start the additional I/Os. ![]() This way most queueing can be eliminated, and overall I/O throughput can be improved significantly. Parallel Access Volumes (PAV) allow z/OS to start more than 1 I/O to each System z 3390 image.
