Need Active/Active solution

Dear Gurus,

My client planning to move some HA products. But they still not sure which one to choose. The requirement is HA should be Active- Active setup in duel DC. They ready to buy some products, I recommend SF cluster but not sure which one is best. Kindly suggest me which combination suits with below products.

Available DC Setup :

1 Active DC ,1 Active near DC and 1 DR location

Products in hand:

1) Oracle & IBM hardware

2)  storage (3 * 20K vmak)

3)  EMC vplex

4) DB - Oracle RAC (11gR2)

Now which symantec HA clustering topology & method can help to achieve 99.99%. To make active-active in HA any minimum perquisites need to maintain from Network, SAN & storage.

How about IBM P780 , EMC vplex with SFRAC for Active - Active- Standby ?

Thanks,

Jay
