Wow. I can't believe a whole year has passed since my last entry. Who has time to blog? When there is so much going on. A little re-cap may be in order since my last blog about Sun's its plan to open source all of its storage software IP.
All I can say is Open Storage has taken the storage world and Sun by storm. Why all the fuss? The attention given to ZFS inside and outside Sun has been astounding. Without even trying, ZFS has catapulted from hype factor to 'must have' in Sun products in record time.
So what is it about ZFS that is better than other file systems? "Them's fighten" words to many folks that have file system expertise with other Sun file system technologies. And yet, despite its detractors and behind all the hype (it can't solve every problem users face and it's performance isn't ideal in some workloads), for most general purpose applications where you need a local file system, ZFS data integrity, integrated volume management and FREE snapshot services outshine all the areas that will get better with time. After all ZFS is a baby in file system years.
In my view there are three fundamental things that make ZFS an ideal local file system for most users.
1. Its tightly integrated into the Solaris ecosystem
ZFS can now be the root file system choice when booting from the the Solaris OS. It is the default file system in OpenSolaris today.
2. Its dead simple to administer.
Anyone can be up and running in less than 5 minutes. This fact often gets overlooked because we'd spend alot of time talking about ZFS internals rather than the things that motivate people to change how they do things today and how file systems could be better deployed today. The "simple factor has helped to drive ZFS adoption, new users and the largest open storage project community on record as evidenced by the growing attendance at the open storage summit held last February in San Francisco.
3. Free snapshots.
No cost to users for additional data services. This fact alone has people motivated to give ZFS and Sun storage another look whether they are considering a Sun appliance based on OpenSolaris with ZFS embedded data services or they are deploying a general purpose server for file sharing.
