Bundle VMWARE 2xESXi + EMC VNXe + TAPE Library + BE/NBU

Hy there

We're trying to create a bundle to Small (really small)  Business,

We have

2 x dual SixCore 128GB RAM

1 EMC VNXe (iSCSI and NAS)

1 x single socket (master server NBU)

1 Tape Library single drive LTO6

1 VMWARE VSphere ESS+ Kit for servers (and sometimes all infra for VDI)

1 Master Server NBU + 2 Enterprise Clients + 1 drive

NBU is getting a little expencive, I do not know aboute BE at all.

does anyone could sugest me an equivalent solution w/ BE?

Could BE could back VMware VDI as well?

Thanks a lot

best Regards
