RocketStor 6328

The RocketStor 6328 converts Thunderbolt from the Mac to SAS to control LTO-5 or LTO-6 tape drives or libraries

Highpoint RocketStor and RocketRAID are NOT COMPATIBLE with LTO-7 or LTO-8 drives
They may work with LTO-5 and LTO-6 drives, but we don't recommend using them.
RS6324L and RS6328L only support SATA devices, they will not work with LTO devices.


The 6328 has two Thunderbolt 2 ports. Connect one to the Mac. The other port can be used to loop the connection to another Thunderbolt device.
There are two connectors for SFF8088 cables. Each connector can control 4 LTO drives with an SFF8088 to 4xSFF8088 breakout cable. Or use a SFF8088 to SFF8088 cable for one drive.

The RocketStor does not support the TLR protocol so it is not compatible with the higher speed of LTO-7 and LTO-8 drives.
If using an LTO-5 or LTO-6 library use firmware v1.8.1.0 as newer firmware v1.8.8.0 will not format and mount tapes.
There are other models like the 6328L, which will not work with any LTO drives.

Checking hardware devices

To check that the Mac can see the RocketStor and LTO hardware hold the alt key on the Mac keyboard, click the Apple Menu and select System Information...

Check for Thunderbolt devices

Select Thunderbolt from the left hand Hardware list. The 6328 should always be there as long as there is 12V power connected to the unit.

RocketStor Driver missing

Now select SAS from the Hardware list. Here the driver has not been installed so no SAS devices are shown.

Download the firmware, driver and WebGUI for the RocketStor 6328 from the HighPoint website.

RocketStor Driver installed

Now the driver is installed and the Highpoint SAS device is shown. Check the firmware revision, we recommend revision v1.8.1.0 as v1.8.8.0 will not work with a tape library.
There is a single SCSI Target Device, this is the Highpoint SAS controller. No tape drives are connected.

Updating RocketStor Firmware

To update the firmware first install the WebGUI, this will put a HighPoint RAID Management icon on the desktop. Open that and then select the Physical Tab.
Check the current Firmware Version, then click Choose File and select the downloaded 6328fw.blf file and click Submit.
When finished disconnect and reconnect the Thunderbolt cable to restart the RS6328.

LTO drive connected

Make sure an LTO drive is connected and powered on, now a SCSI Target Device @ 0 is shown. Here an IBM LTO-5 drive is connected.
YoYotta LTFS will now be able to control this drive.

The System Information page does not refresh automatically. After adding or removing devices Click File, Refresh Information or Command + R to refresh the hardware listing.

LTO library connected

Here an HPE MSL4048 with three LTO drives is connected. SCSI Target Device @ 0 has two logical units.
SCSI Logical Unit @ 0 is an LTO-5 drive, SCSI Logical Unit @ 1 is the library robot. If two logical units are not shown for the Target @ 0 then the configuration of the tape library needs to be set to external control.
SCSI Target Devices 1 and 2 are LTO-5 and LTO-4 drives.
YoYotta Automation will now be able to control this library.
