Hi Paul. Thanks for reaching out. We are still perfecting our design on these, and will be sure to let you know as soon as they are ready. Sorry for the wait but stay please tuned!

Hey Mike,

In Ny,

Do you sell those blue clips for raid card on the funky raid design PE720 Dell server?

How much if you do. Let me know if you can sell those to us.

Thanks for reaching out, Dr. Manweiler, and great question. Unfortunately, OS Support and options for COAX DVR cards are very minimal. That said, there are several analog camera to IP camera converters on the market. A couple of caveats to keep in mind: some of the universal ones don’t work as well across all models, and if you can find one specifically made by the manufacturer of the analog camera you already have, go with that. Also, these converters can be expensive – you may have to do a cost-benefit analysis to see if the cost of the converters exceeds the cost of just buying a new round of digital cameras. I would start with a Google search, “convert analog camera to IP camera.” A couple of product options and literature look like a good place to start. Thanks again, and we hope this helps!

Hi Michael. Thanks for the comment below and the feedback on the storage needed. If you increase the drives on our build to 1 TB, as you suggest, that will give you a total of 10 TB (for only an additional $5 per drive as of this writing). You could even add 2TB SAS drives – although the price is a big jump. If more storage is required, we have the R720, R730 servers with 8 to 12 3.5" drive bays where we can install 4TB, 6TB, 8TB and 10TB drives. The WD storage calculator is a great tool. Thanks for sharing.
As for WD Purple Drives, yes, they are specifically designed for surveillance storage. We don’t usually get them in our refurbishing pipeline, so we recommended SAS (Enterprise) drives as they are built for very high read & write thresholds. (PS, our return rate on hard drives is <1%). Thanks again for this comment – feedback like this helps us make our blog an excellent resource for our customers!

Interesting configuration although the issue that I have trouble dealing with is that I have a good number (10) of old style analog (coax) cameras which work great but for a configuration such as you have put together to work for me I would have to have some type of interface that would accept at least 10 of these hard wired cameras but still provide the capability to allow me to have 8 (currently) IP cameras. Note that almost all of my cameras are at least 2k and most are 4k.

Any thoughts on hardware that can be added to the server you spec’ed out above that could also handle analog cameras?

6TB is nothing. Most of my NDR need at least 10TB for 8 cameras. Also, if you want to work right, I suggest using WD Purple Hard Drives. https://www.westerndigital.com/products/internal-drives/wd-purple-sata-hdd#calculator this page has Calculator Storage link on the page.

Hi Bob. Thanks for the comment. We read the guidance on VMWare’s site, and it looks like, just as you said, future versions of ESXi will lose the SD media boot functionality. Thanks for the heads-up and sharing your YouTube channel – it looks like a wealth of info. We’ve subscribed! Thanks again!

— TechMike


You may wish to note that VMWare has publically said it will no longer support SD media (or USB) to boot VMware ESXi in the future.


P.S. We review Vmware and used servers on our Youtune channel. Search BOB PELLERIN or CTOBOB.

Hi Jared. Thanks for reaching out. The PE M905 is a Blade server. From our experience with Blade servers, the system board is a different design with different dimensions from rack server boards. It would almost certainly not fit. Sorry!

— TechMike

Any way I could install the Dell poweredge m905 into the chassis of an r620
