Note:  You ability to use a GUI to create HyperSwap volumes simplifies creation and  configuration.  To start the process of creating a volume, navigate to the  Volumes  menu, and click the  Volumes  option of the IBM Spectrum Virtualize graphical user interface as shown in  Figure 7-8 on page 279. A  basic volume  has only one physical copy, uses storage that is allocated from a single pool  on one site, and uses the readwrite cache mode. Basic volumes are supported in any system  topology and are common to all configurations. Basic volumes can be of any type of  virtualization: striped, sequential, or image. They can also use any type of capacity savings:  thin-provisioning, compressed, or none. For added capacity savings, deduplication can be  configured with thin-provisioned and compressed volumes in data reduction pools.  To create a basic volume, click  Basic  as shown in Figure 7-10 on page 280. This action  opens Basic volume menu where you can define the following parameters: 7.2.1 Creating basic volumes GLYPH<SM590000> Pool : The Pool in which the volume is created (drop-down) GLYPH<SM590000> Quantity : Number of volumes to be created (numeric up/down) GLYPH<SM590000> Capacity : Size of the volume in specified units (drop-down) GLYPH<SM590000> Capacity Savings  (drop-down): – None – Thin-provisioned – Compressed GLYPH<SM590000> Name : Name of the volume (cannot start with a numeric) GLYPH<SM590000> I/O group Chapter 7.
