Triton Bare Metal Containers FTW!
If you haven't heard of Docker, I'm not sure what cave you've been living in but here's the short story:
OpenSolaris
Linux and Solaris are Converging but Not the Way You Imagined
In case you haven't been paying attention, Linux is in a mad dash to copy everything that made Solaris 10 amazing when it launched in 2005. Everyone has recognized the power of Zones, ZFS and DTrace but licensing issues and the sheer effort required to implement the technologies has made it a long process.
Sun Oracle Webcast Wrap Up
Last night I watched almost the entire 5 hour live webcast announcing Oracle's strategies regarding the Sun Microsystems acquisition. As a near-evangelist for Sun and Solaris, I'm very happy with the deal finally going through and even happier that most of what Oracle said makes sense to me as a customer.
No ZFS Support for EMC Replication Manager
As I originally blogged, I was hoping to use EMC snapshots to perform server-less/network-less backups. EMC provides two main tools for managing snapshots in this type of situation:
- EMC Replication Manager
- EMC PowerSnap Networker Module
The PowerSnap Module supposedly automates taking snapshots for the purpose of backups, while Replication Manager supposedly provides a much more robust package.
With Replication Manager you might create a policy to take a snapshot every five minutes, keep the last 10, and use those for backups whenever necessary.
To make a long story short, Replication Manager is useless for LUNs with ZFS. According to EMC, this won't change in the near future. PowerSnap also has no support for taking snapshots of LUNs with ZFS on them so basically EMC has no server-less backup offerings for Solaris with ZFS.
