We have about 12 Drobo Pro units across our customers. These are connected to dedicated Gbit NICs on our vSphere management servers for the purpose of storing Veeam backups on. Our backups have been horribly slow compared to the performance we saw previously with regular USB hard drives. I ran a test backup on two different customers with it connected via USB instead of iSCSI and it cut hours off the backup. I was under the impression that iSCSI should be substantially faster than USB with a DroboPro. Amy I mistaken?
Most of the Drobo Pro are configured with 8 x 2TB WD Green. The units are connected to the Broadcom or Intel 1000Mbit NICs in Dell 2850/2950 servers or similar. Latest iSCSI initiator is loaded on the systems along with latest Drobo software and Firmware. Drobo’s are static IP’d to a dedicated subnet used just for the Drobo.
