You can add as many as 32 (2 TB) Extents to a VMFS Volume.

Maximum size of a VMFS Volume is 64 TB.

Your best bet would be the iSCSI Configuration Guides and the FC SAN Configuration Guide

The problem is when we add both LUNs to ESX,  the LUN the IBM DS4800 and the LUN IBM DS8300 , the ESX server fails.

Are both IBM DS4800 and IBM DS8300 different storage arrays ?

How are they connected ? (Network Architecture)

What type of SAN is it ? (FC or iSCSI)

Yes , we have in the ESX server 2 HBA with adapter FC IBM DS4000 2-pt PCI-X 4 Gbps dual port
From the server ESX have four connections HBA1 dual port and HBA 2 dual port
The zones are
HBA 1:
Controller A DS 4800 to WWN1
Controller B DS 4800 to WWN2
HBA2:
Controller A DS 8300 to WWN3
Controller B DS 8300 to WWN4
The architecture is all the fiber channel , the SAN is FC
