Maximum number of Cache batteries per EVA4000 controller

Hi Experts

What is the maximum number of cache batteirs supported on an EVA4000 (per HSV200 controller)

The EVA4000 starter pack currently only has one cache battery per HSV controller, but I wish to upgrade it to two cache batteries per HSV. Is this possible?

Thank you

The maximum number is one.

'starter pack' just means that it is a predefined package with controllers, disk enclosure(s), disk drives and licenses which allows the customer to order everything under one number.

bad cut and paste, sorry.

Two batteries are used on the EVA8x00 and a single battery is used on
the EVA6x00 and EVA4x00.
