  Each volume copy can use different encryption methods (hardware and software). It is also 
  allowed to have volume copies with different encryption status (encrypted versus 
  unencrypted). The encryption method depends only on the pool that is used for the specific 
  copy. You can migrate data between different encryption methods by using volume migration 
  or volume mirroring. 
  
  **12.2.3 Encryption keys**
  
  Hardware and software encryption use the same encryption key infrastructure. The only 
  difference is the object that is encrypted by using the keys. The following objects can be 
  encrypted: 
  
  <html>
          <head> <meta charset="UTF-8">
          <style>
          table, th, td {
              border: 1px solid black;
              font-size: 10px;
          }
          </style> </head>
          <body>
          <table frame="hsides" rules="groups" width="100%%">
              [html]<thead><tr><td>PTUUIS ( SUIIWdIB BTICIYJUIIUI )</td></tr><tr><td>• Child pools ( software encryption )</td></tr></thead><tbody><tr><td>• Arrays ( hardware encryption )</td></tr><tr><td>Table</td></tr></tbody>
