  • Page 37: Chapter 3. Understanding The Storwize V7000 Battery Operation For The Control Enclosure

    The batteries within the control enclosure provide the power to write the cache and state data to a local drive. Note: Storwize V7000 expansion canisters do not cache volume data or store state information in volatile memory. They, therefore, do not require battery power. If ac power to both power supplies in an expansion enclosure fails, the enclosure powers off.
  • Page 38: Maintenance Discharge Cycles

    Important: Although Storwize V7000 is resilient to power failures and brown outs, always install Storwize V7000 in an environment where there is reliable and consistent ac power that meets the Storwize V7000 requirements. Consider uninterruptible power supply units to avoid extended interruptions to data access.
