I saw something wonderful and new at NAB today. The Accusys ExaSAN Thunderbolt shared storage shouldn’t exist but there it is. With 16 x 4TB drives and 4 Thunderbolt ports out the back to connect 4 clients (one of which could be a Mac mini acting as a Xsan 4 controller). That leaves 3 spots for Mac clients for a small editing SAN or post-production workflow. Prices to be revealed soon, I hope. Very interesting for small setups.
Finally!
Yes, Apple has restored the ability to set a user and system umask in OS X 10.10.3. This is a huge fix for users of shared storage. Xsan and all SANs where users want to be able to share files, projects and all things without using ACLs or any LDAP directory. This is great. I am jumping up and down. So happy. So many people wanted this. Anyone using shared storage have been demanding this since the upgrade to Yosemite. 10.10.3 is out today and we will be happy.
