Frequently Asked Questions

Which models and form factors are in the Gen4 line?

U.2/U.3 single-port: J750/J770 (CORE 7) and J760/J780/J761/J781 (TITAN 7); U.2/U.3 dual-port: J760D/J780D; AIC HHHL Gen4 x8 add-in cards: J200A/J230A.

When should I pick 1 DWPD versus 3 DWPD?

Pick 1 DWPD (J750, J760, J761, J760D, J200A) for read-intensive work such as general servers, Ceph, virtualization and object storage; pick 3 DWPD (J770, J780, J781, J780D, J230A) for databases, logging and write-intensive workloads.

What capacities and speeds does the Gen4 line offer?

U.2/U.3 models span 1.6 TB to 30.72 TB (J761 tops out at 30.72 TB) at 7.4 GB/s sequential read and up to 1.75M IOPS; the AIC models J200A/J230A use Gen4 x8 for 13.5 GB/s sequential read.
