First off, I have no affiliation with any of these companies mentioned.

So today I went walking into my Canada Computing supermart asking some tech question. I was taken over to this QNAP Turbo NAS box which I must say is very sweet. It is a self contained NAS unit that can handle over 15 TB of space with 4 external drives. It also includes your basic operating system like Windows Server or Linux which would includes MYSQL Server as a data store. Wow! It also includes your packages for FTP, printer server, and other environments including a Python or Java runtime environments. Did I mention these can all be shared among one system? It is also VMWare or Hyper V ready for virtualization. This is really good but the only two drawbacks are:

1. It is a ATOM processor which could be kind of slow

2. The price might be hefty for those but the ones I looked at ranging from $800-$1100 each. You are still saving on the software and hardware alone!

As for high frequency trading potential, I would recommend this for developing/testing only. If the regulators step in to delay all trades by a few seconds, this box could potentially be useful for even a production environment. Notice I say potential only.  This would definitely be a decent fit for my potential Trading-Shim which uses MYSQL as the backend for data store of market ticks.

This could get very interesting with this device.

Join my membership now to figure out if I use this thing.

I have a very large NAS (IBRIX) environment and would like to find out how to locate who is using up all of the space

Question – I have a very large NAS (IBRIX) environment and would like to find out how to locate who is using up all of the space? Linux based commands are there however what tools are out there?

If you have quotas enabled, you could do something like this in bash:

for i in (LIST OF ALL USERNAMES); do echo $i; quota $i | grep FILESYSTEMNAME; done

And then do some post processing.

If you don’t have quotas, then you’re going to have to spider the filesystem in some fashion.

Also, maybe IBRIX support (That’s HP now, right?), might have something to recommend.

EMC has some tools – VisualSRM, and NetApp has something to in the OnCommand. HP may have something, not sure.

Try “agedu” also.

my experience is that “spidering” (with du or otherwise) large remotely mounted filesystems (NFS or otherwise) is anything but cheap.

quotas (user, tree, group , in some cases user under tree) in report mode (enforcement mode may be off) remain the easiest way

under Linux, repquota will usually report for all users

some filesystems (i am unfortunately not familiar with IBRIX) have specialized quota reporting commands
