NASBIT© is a Licensed trademark of SimplyNAS. The acronym stands for Network Attached Storage Burn in Testing. This term is used to describe the process of testing new Network Attached Storage (NAS) hardware and firmware plus any installed hard drives for faults before putting them to use in a live environment. This is done by running 'Stress testing' software for a stipulated period of time on the unit, often 24 to 48 hours, but longer if needed.
When we receive an order for a NAS system pre-installed with hard disk drives it’s prepared and configured with RAID followed by burn testing to ensure the entire system undergoes a thorough examination before shipment thus ensuring the server passes all tests to the highest standards set by us. Should the system hardware or any associated components fail at any point during the testing cycle the system is pulled and returned back as faulty to our relevant vendor partner and a new system and drives are then prepared and testing commences once again. The process seems simple but setting it up is far from easy.
Hard Disk Drives
All Hard disk drives are pre-tested prior to integration; the smallest of faults, be it tolerable within industry standards, are classified by us as faults. The hard drive is rejected and eliminated from the process and again returned back to source as a D.O.A. (dead on arrival). We continue to select drives from different batches, so as to eliminate any bad batches that may have been produced during manufacturing.
One integrated the drives are put through a vigorous routine that includes stress testing, including temperature tests and a host of read/writes to ensure the drive platters are stressed to the nth degree.
First, when the new server is turned on, we boot off of the network, and proceed to run the memory test that takes its sweet time, almost 10-12 hours dependent on manufacturer and model.
The appropriate RAID level is set and the system awaits completion of RAID synchronization. Once completed the NAS server undergoes numerous re-boots and a deletion of original RAID and a final re-build of RAID level again.
Why is NAS Burn in Testing (NASBIT©) necessary?
If within the designated time span the NAS servers are still running and with zero faults, it is considered suitable for rolling out to our customers. If there is a failure of any kind the systems is replaced with a new one, including hard drives and the process starts again, until the NAS servers passes with ZERO faults.
You would normally expect that this level of testing would be completed by the hardware manufacturers and so these tests shouldn't show up any faults. In our experience of testing hundreds of machines we do find faults, and we do send systems back.
The reason it is so important to perform this level of testing on NAS servers is that the uptime demands are so high. The slightest faults will cause outages and downtime. Once a NAS server is deployed, never again will you have the opportunity to take it offline and perform such detailed testing. Even if it were to crash, there is always a demand that it be put back online as quickly as possible, not left offline whilst thorough diagnostics are completed.
Always remember this is hardware and failures can and will occur even after burn testing has been carried, that is a fact of life we cannot avoid, but we do try and eliminate some of the hassle factor with testing. Thank you for buying from us, we truly appreciate your custom.
