I recently introduced ESXi to my environment and am chomping at the bit to deploy my DroboPro as a datastore for my virtual machines; I’m out of storage capacity on the server’s direct-attached drives but I have the DroboPro locked and loaded full of new drives.
On my first attempts to mount the DroboPro volumes in ESXi, I noticed rescan and refresh functions within vSphere were slow to respond. I got everything connected and talking without further issue, until I tried to transfer some unused files from my server’s internal storage to the DroboPro (local SCSI drives to DroboPro on iSCSI)…the speed was beyond dismal and the connection completely dropped several hours (!) into the 40GB transfer. My Drobo was unresponsive and I could only get it to remount in vSphere after a hard reboot/power cycle.
The bottom line is I’m hoping the community might be able to provide me with some ESX/ESXi tips and tricks to get things running smooth. I know Data Robotics just got certified with VMware within the past week, but the latest firmware and dashboard had no effect/improvement…I know multi-host iSCSI support is still forthcoming but I’m just after reliable speeds/reliable connections on a single host at this time.
I just tried to pull a diagnostic file from the unit and it froze again
Disks: 4xWD Green 1TB, 4xWD 160GB
Format: VMFS, 8MB block size
iSCSI: Dedicated NIC, Dedicated iSCSI vSwitch, connected to ESXi by crossover cable, manually assigned IP
Dual-Drive Redundancy: Enabled
Volumes: 2x 2TB
Volume Usage: 0% on both volumes (I have gone through multiple resets to default settings)
Thanks in advance for any help…VMware and DR should have more info coming now that they’ve formalized a partnership/certification but I need to make my $2k+ investment start returning, like, yesterday
