Last week I was talking to an friend, he is an system administrator with a large insurance company in the Netherlands. He told me that at his site there is a huge problem with cleaning up home- and profile folders. This problem was never really acknowledged because there was always enough storage. Recently they have been receiving messages from the storage management system that they are reaching the limits of there storage capacity.
In the category “Sumble Upon”, I came across a nice piece of software which let you forget about Dropbox, SkyDrive, GDrive, etc. Because now you can build your storage-cloud on premises.
Nowadays there is a proliferation of providers, if you want some storage in the cloud to store your photos, videos, documents, etc. And as always every provider has its own advantages and limitations.
Now we could use a Synology NAS or a Pogoplug to create a storage-cloud on premises, but we want to be in control and we want to try, play and experience building our own storage-cloud. It’s just like version 2 of building our own NAS, not just buy a NAS but build one with OpenFiler or FreeNAS.
When you are using IBM equipment there is a big chance that you will use IBM related software to manage the environment. In a large environment you can use IBM Tivoli Storage Manager (TSM) for Virtual Environments to make back-ups of your virtual machines. IBM says that:
Tivoli® Storage Manager software provides a wide range of storage management capabilities from a single point of control, helping companies ride the information tidal wave.
Early this year they’ve added a new product to the Tivoli Storage Manager, IBM storage management software called IBM Tivoli Storage Manager for Virtual Environments (TSMVE). This is their product for making back-ups and to recover virtual machines.
You would think that a big company like IBM jumped on the train of virtualisation when it was leaving the train station but in my opinion that’s not what they have done!
When i was replacing our storage in our Lab environment (VMware Lab manager 4.0) i got to the point where i must move the templates we have in the environment I looked in the resources and setting of lab manager (Yes as you i don’t go to the manual first) but there is no option to move the lab manager templates form lab manager. This must be don by a tool called SSMOVE and must be done from the Lab Manager server.
Storage is one of the 4 core design parts that has a big impact on the performance and the cost of a virtual environment. I was looking for a way get some demands for the storage i wanted in my environment. When you talk about storage demands you talk about IOps. IOps stands for Input Output operations per second and is a common benchmark for Hard disk (including solid-state drives). In search of answers i found a lot of information but at two create blog, of two people how are well known with in the VMware community, i found the total picture a was looking for. The blogs belong to Josh Townsend of VMtoday and Duncan Epping of yellow-bricks. The links of the related article of the blogs are at the bottom of this post. They collected the information i also found divided over the web. Now i can just link to those pages but this is also a overview for my self.
Recently some unfortunate events happened which made me think about the safety of my files.
So what happened? Well, because I’m using both my laptop as my home PC the documents needed to be on both. And they needed to be consistend and safe, of course. So I created a rather complex solution where a local USB disk made a backup of my laptop and a NAS at home that synced the laptop and desktop. This resulted in a situation where I had 4 locations with the same files… Oops.
The unfortunate events that got me thinking were:
a) It took a while to sync all the data to the NAS through Wi-Fi;
b) The NAS got broken (after 6 months…);
c) Installing XenClient resulted in an empty laptop,
There had to be a better way, something less complex. After hearing all the buzz about “the cloud” I figured this might be a solution, why not putting my data “in the cloud”? After some research (and experimenting) I ended up with Dropbox.
