After the recent announce of  new Equallogic storage I’ve notice some tweets that need more  clarifications.

To take advantage of new vStorage API for vSphere you do not need the new storage, but only the firmware that support the required feature:

  • VAAI can be used also in vSphere 4.1 (only in the Enterprise and Enterprise+ editions)  both with firmware 5.0.x or 5.1.x. With the new 5.1 firmware a new version of VAAI is implemented with a new feature for thin provisioning (but in this case it’s also required vSphere 5).
  • VASA can be used only with vSphere 5 and the new 5.1 firmware, but old with a old Equallogic storage (check controller compatibility for the 5.1 upgrade).
  • The new related software, like for example the EqualLogic Host Integration Tools for VMware 3.1, are not strictly required to use Equallogic in a virtual environment or to use vSphere integration.
