GLYPH<SM590000> Epic (FC0964), VMware VAAI (FC0965): For clients who want to use the Epic healthcare software or VMware vStorage APIs for Array Integration (VAAI), these features must be selected by the IBM marketing representative. For the VAAI XCOPY/Clone primitive, the PTC (FlashCopy) license (in the CS bundle) is also needed. 

GLYPH<SM590000> IBM ProtecTIERfi indicator (FC0960), IBM SAN Volume Controller (FC0963), IBM Storwize V7000 virtualization (FC0961), N series Gateway (FC0962) indicator: If the DS8900F is used or virtualized behind any of these data deduplication or virtualization devices or a NAS gateway, select the correct feature to indicate this device. 

GLYPH<SM590000> When installing the DS8950F Expansion Frame at distance from the base frame (=up to 20 m), use the FC1341 feature cabling option to make sure that adequate cabling is provided. 

GLYPH<SM590000> The Front and rear door lock kit, FC1014, is another example for a feature that can be ordered without an extra license key, and so are the various door options (Standard FC1105/1107, Space Saver FC1106), the Top-exit bracket for fibre cables FC1401, or the exemption from the Remote Code Load process FC0990. 

For more information about these features, see the IBM DS8900F Introduction and Planning Guide , SC27-9560. 

## 9.1.2 Licensing cost structure 

For the three possible license bundles, the following general guidelines apply: 

GLYPH<SM590000> Base Function (BF) license 

The license needs to be equal to or greater than the total physical capacity of the storage system. Select the full raw capacity and order the number of TBs to support the total physical capacity of your storage system. 

GLYPH<SM590000> Copy Services (CS) license 

The license can be equal to, less than, or more than the total physical capacity of the storage system. You need to license the TBs that you actually use in copy relationships. 

GLYPH<SM590000> z-synergy Services (zsS) license 

The license can be equal to or less than the total physical capacity of the storage system, but order less only if you have a mixed machine FB/Open and CKD/mainframe. You need to license the full CKD/z raw capacity for zsS, that is, the physical capacity of all ranks that will be formatted as CKD ranks. 

## Copy Services license specifics 

You can order the CS license to support the total usable capacity  of all volumes that are involved in one or more copy services functions. However, this sort of subcapacity licensing (less than the total physical raw capacity) requires capacity monitoring and a steady remote connection on the client side. 

Important:  With the CS license bundle, only order subcapacity licensing, which is less than the total physical raw capacity, when a steady remote connection for the DS8000 is available. 

By using a remote connection for call home, the CS license can be based on the usable capacity of the volumes that will potentially be in CS relationships. This amount typically is less than the total physical capacity.
