Do you have lots of LTO tapes? Do you need to create large archives and restore media efficiently?
Put the tapes into an HPE, IBM, MagStor, Oracle SAS, Overland-Tandberg, Qualstar, Quantum, Spectra, StorageTek or Tandberg Library and let YoYotta Automation take control
YoYotta Automation can control one library and up to 4 LTO drives, these can be any mix of library or standalone
Automation tapes and drives
YoYotta Automation monitors the library for changes and shows all the loaded tapes on the left, the empty slots on the right. The tape drives are shown at the bottom. There are buttons to manually move, format, mount and eject tapes, but YoYotta will do all this automatically.
YoYotta Automation supports up to 4 drives and 160 tape slots. Both mail slots and ordinary slots can be used for tapes, so no spaces are wasted. However it can be quicker to open just the mail slot on a library so the Export button will automatically move a tape into a mail slot.
Why a limit of 4 drives? With the faster speed of LTO-7 and LTO-8 it’s hard for a single computer to provide enough bus bandwidth to keep 6 restores or 3 jobs writing to dual tape sets. This is a typical workflow for a 6 drive library and is before looking at NAS/SAN speed. There are YoYotta customers with larger libraries and by partitioning the library you can use two or more YoYotta systems. The recent Mac mini is ideal as an Automation Mac. Splitting up the workflow like this maintains high performance. The new YoYotta Metadata Server allows each system to sync it's part of the project.
All tapes must have barcode labels
The labels have a unique 6 character code with either L5, L6, L7, M8 or L8 on the end for LTO-5, LTO-6, LTO-7 or LTO-8 tapes.For example 123456L5, ABCDEFL6, YO1234L6, 17376AL5.
YoYotta will use the barcode to format the tape. No need to manually enter the barcode. This is an LTO standard, using more than 6 characters means that the tapes will be difficult to use.
We can supply LTO tapes in Europe at great prices with custom YoYotta labels printed on durable plastic. They have a standard barcode, plus a globally unique NFC chip that allowing easy tracking. You can add unique text labels on the left as shown opposite. So you can clearly label Main and Safety, or add a project ident. Unlike other labels each tape can have a different code, you are not limited to a set sequence.
IBM make all LTO-7 and LTO-8 mechanisms, so we supply IBM Barium Ferrite tapes for perfect compatibility.

Select the tapes needed for the archive
Start the archive
Blank tapes will automatically be formatted with the correct barcode, saving time.
Add more tapes for larger archives
Add as many tapes as you want as destinations. Make sure you add them to COPY #1. This will make a single copy spanned across multiple tapes.
Spanning larger archives across tapes
Tapes will only be used if needed and they will be loaded and formatted automatically (if blank) then mounted.
So always add a few extra tapes to the job.
So no need to open the LTFS panel.
On completion the database will show which assets are on each tape.
Connecting a library to a Mac
Drives for libraries are available with SAS or Fibre Channel interfaces.
Use SAS libraries, they are cheaper, they use more durable cables, there is no configuration and SAS gives the same performance.
To connect a SAS or FC LTO-8, LTO-7, LTO-6 or LTO-5 drive to the old MacPro use the ATTO ExpressSAS H680, H1280 or Celerity FC PCIe cards from ATTO.
H644 and H608 cards can also be used, but ensure they have the correct SAS connectors for your drive.
Each SAS connector can control up to four SAS drives using a SFF8088 to 4x SFF8088 cable.
See this link for more details on the ATTO.
To connect a Thunderbolt Mac to a SAS LTO library use the ATTO H680 or Celerity FC cards inside a Thunderbolt PCIe expansion unit, like the Sonnet Echo Express SEL.
The Sonnet Echo Express SEL is a compact Thunderbolt enclosure that holds a PCIe card like the ATTO H680. A lot of our customers use this to connect to a desktop SAS LTO drive or tape library. Get the Thunderbolt 3 unit as this means that there is plenty of bandwidth for multiple LTO drives and also daisy chaining other Thunderbolt units. The Apple TB3 -> TB2 adaptor allows connection to older Thunderbolt 2 Macs. There are also other units that hold more than one card.
ATTO Thunderlink SH1068, SH2068 TB-SAS, ThunderStream SC4808 adaptors, R680 or R644 PCIe RAID SAS cards do not support TLR which is a required protocol. So they are not compatible with LTFS running on any operating system.
Highpoint RocketStor and RocketRAID devices are not compatible with LTFS + LTO drives.
The Highpoint 6328L is a SATA protocol interface. It has Mini-SAS connectors, but does not support SAS protocol. So this does not work with any SAS RAID or tape devices.
The Highpoint 6328 is a SAS protocol interface. But it does not support TLR protocol, so it cannot be used with LTO + LTFS.
It is not possible to set the Oracle SL150 control path to use a FC drive. To use it with macOS, there has to be at least one SAS drive in this library and use this as the control path.
mLogic mBridge SAS unit
An alternative is the mBridge from mLogic connects a Thunderbolt Mac to a SAS LTO tape library. It is rack mountable and has a built in power supply. There is also a FC version available.
YoYotta can supply the mBridge, contact firstname.lastname@example.org for details.
