The 11 hospitals in the Capital region of Denmark have online capacity of 500 terabytes as well as 1.5 petabytes of archiving and backup data. And the need for storage keeps growing. Its a task Henrik Schmidt, Storage Team Assistant Engineer, can tell you all about.

[Henrik Schmidt, Capital region of Denmark]
The Capital Region of Denmark is conglomeration of all the hospitals in the Copenhagen area.
It consists of 11 hospitals, 4 or 5 large ones, and a few more smaller ones, with about maybe 1.5 million people as potential patients.
We have huge data needs. Our online disk capacity at the moment is about 500 terabytes and backup and archiving is 1.5 petabytes of data.
Well, obviously, our storage needs grow about 30% to 50% per year, which is not expected to slow down at any time, and so of course, as the storage need rises, so does the storage cost. So we are already now implementing tiered storage, where we have at least three different tiers of disk storage, plus as I said before, a huge amount of tape storage. We have in four sites what we do the backups, and we have about -- I dont know -- 4,000 or 5,000 tapes available all times. These are online tapes, or near line as you would call it.
Our biggest challenge has been to consolidate all these systems into something we can manage with very few people. Because were only four people in the whole storage team. Luckily, for us, when these three units were combined, they had incredibly diverse systems. One of them was only running Windows and Microsoft, the one where I came from myself had the most heterogeneous environment you could think of, and the third one, cant even remember. But they had one thing in common. And they were all running TSM as a backup product, which is a huge advantage for me as a TSM administrator. So it wasnt such a huge leap to start consolidating these systems.
...one of the things Ive been working on is looking at all these, we had hundreds of different backup policies, because we had the systems, even though they were all running TSM, they had very, very different backup policies and they had a lot of backup policies; one for Notes backup, one for Exchange backup, or maybe even like four for Notes backup and five for Exchange, and ten for file backups, and I tried to merge these into something like 10 policies in all, 10 or 15, which are then covered to our service level agreements, because even though we are part of the corporation as a whole, we also see the hospitals as our customers, and we have SLAs with them that we need to uphold, and the better the SLA, the better the backup. And we can do that today.
...It's the ease of use of these systems is very important. An enterprise level backup system is not a simple thing. It is a very complex thing. And but we have a lot of tools, so we can monitor how things are working, and because we can monitor everything from the same software, from the same website, its much easier to find the recent, find the cause of any problems for instance, we can move resources around. If we have an underutilization at one place and a lack of resources somewhere else, we are able to move these around.
One of the things we are going to look at next is data de-duplication, because we have so many systems and the data and a lot of it are exactly the same. And today, our backup systems do not take this into account, so we have maybe like 1,000 copies of the same system files, which is not a good way to utilize your storage. So this is, you can do this many places in your storage network, in your data center, but the backup system is a good place to do de-duplication. So thats one of our next projects.
