3x HP AJ764-63002 Storageworks with R730

[berkbal]

Hello, i was using 1 x HP AJ764-63002 Storageworks 82Q 8Gb Dual Port PciE with R730. Now i wanted to upgrade my storage network little bit and im trying to work around with 3 x HP AJ764-63002 Storageworks 82Q 8Gb Dual Port PciE (For 3 Shelf seperately connected) but when i put 3 or 4 8G PCie, no other than 2 x 8Gbps works. I have tried with another R730 but result was same. Is there any knowledge about this? I have read that R730 can support 4 Full Lenght HBA on Dell Specifications list

Specs :

R730
E5 2667 V3
32x24 GB DDR4 2133MHZ ECC RAM

Shelfs:

Network Card For Shelf connection:

HP AJ764-63002 Storageworks 82Q 8Gb Dual Port PciE


Thanks for all.
