ioSafe N2: A Disaster-Resistant Synology DS213
by Ganesh T S on March 4, 2013 12:00 PM ESTPerformance Benchmarks - Single Client
Benchmarks were run under both Linux and Windows for evaluating performance under single client scenarios. Intel NASPT was used under Windows and IOMeter was used under Linux.
For iSCSI performance evaluation, a 250 GB target was set up and mapped on the benchmarking machine.
A CentOS 6.2 virtual machine was used to evaluate NFS and CIFS performance of the ioSafe N2 when accessed from a Linux client. In order to standardize the testing across multiple NAS units, the following parameters were used to mount the NFS and Samba shares:
mount -t nfs NAS_IP:/PATH_TO_NFS_SHARE /PATH_TO_LOCAL_MOUNT_FOLDER -o async,hard,proto=tcp,noac
mount -t cifs //NAS_IP/PATH_TO_SMB_SHARE /PATH_TO_LOCAL_MOUNT_FOLDER -o directio
Note that we have not tried to optimize NFS performance for the NAS. In order to keep things as uniform as possible, we will just look at comparative performance on the basis of the default mounting options combined with the above (which are set to avoid caching effects on the client side). The scripts available here were run on IOMeter. The graph below presents the various results.

Well, all I could find about the drives is that they are rated for operation between 5°C and 55°C. Not sure what ioSafe means.But I have to say, I find it hard to believe that any enterprise would subject their HDDs to non-climate-controlled rooms. So staying below 30°C environmental temperatures should not be a problem in any enterprise situation.

That particular series of WD enterprise drives (FYYZ) runs hotter than most. Both Synology and ioSafe recommend a 30C operating environment in order to maintain 55C or lower on the drive PCB. Hope that helps!-Robb Moore

I get your point although I'll be a great number of enterprise class drives are not installed in purpose built rooms serviced by hundreds of thousands of dollars worth of HVAC equipment.random2 - Wednesday, March 6, 2013 - link
*For the ioSafe N2, an updated version of the DataCast component is being used. This design allows for more water to be part of the mixture, and we can even see water droplets forming on the inside after operating the unit for a short time. The more water we have in the surrounding material, the better is the fire resistance.*Since this just seems to be so counter-intuitive to most of us working with electronics, can you shed a little more light on how ioSafe came up with this idea for cooling etc. I realize the actual drive housing must be hermetically sealed, but this is still pretty cool stuff.

I had some coverage of the DataCast and other related components in the SoloPRO review: http://www.anandtech.com/show/5731/iosafe-solopro-... : DataCast is based on the final patent in that page (a super-saturated enclosure made of gypsum or similar material). Hope that answers your questions.random2 - Thursday, March 14, 2013 - link
Thank you Ganesh...Appreciate the link a great deal.Cheers.
