4. The default settings for Access Bandwidth Weight and Storage Efficiency Hint produce good
volume organizations for each redundancy setting that use some, but not all, drive resources.
If you change these settings (see Table 5-4), the number of members chosen for the volume
depends on the number of drives available when the volume is created. Small settings use a
small number of members. As setting values increase, the number of members increases
slowly. When maximum values are reached, the xStack Storage Array uses all possible drives
in the volume’s pool and the
Available Pool for a volume. (Spare count is the only limit to
the number of drives obtained from the Available Pool .)
5. Click the Finish button. The main screen reappears, the volume you created appears under
Blade A Base Pool in the Logical Resources tab, and a plus sign appears next to Blade A
Base Pool . Clicking the plus sign displays the volume you created.
