The Case for buying an Integrated NAS System from SimplyNAS
Buying a NAS doesn't have to be complicated or stressful. This may only occur at times when looking to buy a diskless NAS as the risk element of receiving a faulty NAS or drives are accentuated. Nothing wrong in buying a diskless NAS and adding your own drives, the savings made may offset the inconvenience of receiving faulty NAS/Drives and having to go deal with returns, or does it? The argument against buying a diskless and self-populating with drives is quite compelling.

What is NASBIT?
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 for faults before putting it to use in a live environment. This is done by running 'Stress testing' software for a stipulated period of time often 24 to 48 hours, but longer if needed.
When we receive an order for a NAS system pre-installed with disk drives it's prepared and configured with RAID followed by burn testing to ensure the entire system undergoes a thorough examination 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 of the testing cycle the system is pulled and returned back as faulty our relevant vendor partner, 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.
Memory
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.
RAID
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.
NOT AVAILABLE ON DISKLESS UNITS - ONLY FOR SYSTEMS PRECONFIGURED WITH HARD DISK DRIVES
We try our best to get orders shipped as quickly as possible and if something is not in stock at our FL warehouse, we can ship directly from our suppliers usually within 1 - 2 business days, if not the same day. However, due to the current situation with the Coronavirus, some manufacturers are experiencing stock constraints, shipping delays due to warehouse closures, delays in customs or other unforseen circumstances which can sometimes delay an order as stock levels can change hourly. We understand that your order may be urgent, so if you want to check if something is in stock before you place your order, please call us at 407-960-4690 during our normal business hours of 9-6PM EST. We also try to be transparent on the site with availability and shipping times. We do sometimes make mistakes and greatly appreciate your understanding if this occurs. Please allow some grace and patience as we work through the difficulties and challenges of communicating with our suppliers to keep up with supply changes.
So when can I expect a shipping notification for my order?
- Diskless orders that are in stock will ship same day if placed before 2pm.
- Diskless units that are not in stock we will ship directly from our suppliers warehouses. This could delay shipping by 1 - 3 business days.
- Configured systems are considered special order. This means that they are not already pre-built and ready to ship when you place an order. When you purchase a configured system from us it will not ship out for at least 2 - 3 business days due to the time it takes to pick, assemble, test, RAID and prepare your order for shipment. If we do not have one of the components on the build, that will further delay shipment as we have to wait for stock to come to us. You will receive updates for the order as it goes into testing.
When will my card be charged for an order?
We do not immediately charge your credit card when you submit an order, instead a temporary hold is placed on your card for the amount of the purchase. If everything is in stock, we will charge your card and process you order for building or shipment. Should there be a delay of some sort, we will notify you by email with the ETA and ask for approval to charge your card and process your order. Please be advised that we cannot allocate stock to you without prepayment. So, if you approve the ETA, we will immediately charge your card so that we can secure the stock from our suppliers. Once this charge occurs, any cancellation will incur a 3% fee.
Security and Payment Verification Requests
We take customer security very seriously as fraud and chargebacks are costly. In order to protect you and keep our costs to a minimum, we may ask you to verify your identity when you place an order. If your billing and shipping differ, or if the billing and shipping parties differ and we can't veryify you as a legitimate business, we will send a request by email with a link, asking you to upload documentation for us. We understand that this may make some people nervous, but you are sending your files to the same secured server as your payment and no one can access the files except for the staff who verify them. Your files are purged from the server within 120 days of payment date. As we cannot physically verify your identity when you place an order, this is the only way for us to accomplish this so we ask that you complete the verification as we won't be able to process your order until this step is completed.
