Appendix A — Network File Interface Ejecting Tapes to be Read in a Non-BlackPearl Environment
September 2017 User Guide — Spectra Verde Array
161

If the BlackPearl system is running software version 3.0 or later, then
the system has Advanced Bucket Management (ABM) capabilities.
When using an ABM ‐ enabled system with NFI, you must first
configure buckets on the BlackPearl system, and configure data policies
for the user using NFI to transfer data to the system. See the Spectra
BlackPearl User Guide for instructions on creating buckets and
configuring data policies.

If you plan to modify files on the Verde share configured for NFI
replication, you must configure the BlackPearl system as described in
Configure a BlackPearl System for Versioning on page 162 . If you do
not plan to modify files on the Verde share, skip to Configure Network
File Interface on page 165 .

If the target BlackPearl system is configured to transfer data to tape,
make sure the tape library does not contain WORM (Write Once ‐ Read
Many) media. The BlackPearl system is not compatible with WORM
media.

The BlackPearl system stores data on LTO ‐ 5 or later generation tape media
using the LTFS format. If you do not plan to eject tapes, or you plan to eject
tapes and then move them to a different BlackPearl system, you do not
need to follow any restrictions when configuring your system. However, if
you plan to eject tapes and read them in a non ‐ BlackPearl system, you
must adhere to the following requirements:

You cannot use the Amazon S3 MultiPartUpload command to write
data to the BlackPearl system. This command breaks files into smaller
chunks, which cannot be restored by a non ‐ BlackPearl system.

Blobbing Enabled should be cleared when configuring a data policy.
Blobbing allows an object larger than 1 TB to be broken into multiple
blobs and then stored on multiple tapes. Tapes created with blobbing
disabled are always readable by a non ‐ BlackPearl system; tapes created
with blobbing enabled may not be readable by a non ‐ BlackPearl
system. With blobbing disabled, all files must have a size of 1 TB or less.

The LTFS file name option must be set to Object Name when
configuring a storage domain. This setting configures LTFS file names
to use the format { bucket name }/{ object name }, for example bucket1/
video1.mov. If the tapes are ejected from the BlackPearl system and
loaded into a non ‐ BlackPearl system, the file names match the object
names. If you do not configure this option, object names are assigned a
UUID string, which is not human readable.

The Keep Latest setting cannot be used for a data policy which uses a
storage domain configured with the LTFS File Name option set to
Object Name.
