      @creayt Welcome -

      Have you looked at Cloud@Cost? They have some good options available and are also a member here at ML.

      Hadn't heard of them, but I'll definitely check them out. For my current project however I'm already a pretty penny deep in hardware purchases that can't be rescinded. Thanks for the link though, I'll def. keep them in mind in the future.

      I'm David, heard about ML from Scott after stumbling onto the SMB IT Journal recently. I'm a long-time web developer looking to up my server game and preparing to deploy an R620 for personal projects. Excited to participate here.

    • RE: How should I determine exact over-provisioning levels for 1TB Samsung 850 Pro SSDs to be used in a Raid 10?

      @scottalanmiller Interesting. The approach in that link seems to be different than what I've read elsewhere, which is that you set overprovisioning on each SSD before adding them to a virtual disk ( array ), and that each drive will use that allotment internally to maximize its individual performance and longevity. The result being that each drive shows a lower capacity available for the virtual disk use before you create it. That link seemed to say "leave some of the total, available-to-the-virtual-disk-itself capacity unused as part of the virtual disk assembly", which to me seems like it implies that the raid controller itself will somehow maneuver that unused pool of space, unless doing so just means the drives will, but it seems like if you do it at the virtual disk level how can you be sure the unused portion would be split across all drives evenly, and not just be the last drive or so of the array? I'm new to servers and learning stuff at every sentence, so the way I'm seeing this might be off.

      Just consolidated a 3x 27" setup into a single 5k ( running at 3840x2160 on Windows for the moment ) rig. Other than it being a lot slower than the T110.2 I used to work on, I'm loving the simplicity of a single monitor.

    • How should I determine exact over-provisioning levels for 1TB Samsung 850 Pro SSDs to be used in a Raid 10?

      Planning on using Samsung Magician to adjust the over-provisioning levels on 6x 1TB Samsung 850 Pro SSDs to be used in a single Raid 10 on a 1U Dell R620. The server has 10 total slots and I'm hoping to add an additional 4 drives to the array at some point in the future. The controller is a Perc H710P Mini w/ 1GB, and I'll be running Server 2012 R2. Full specs at the bottom of the post.

      From what I understand:

      1. Hardware raid controllers don't support TRIM.
      2. The higher the proportion of the total capacity you dedicate to overprovisioning the faster the performance will be because of how SSDs shuffle data around to level wear, and the longer the life of each individual drive will be.

      I don't need the maximum capacity of the drives so can get pretty aggressive on the amount dedicated to OP, at this point the only thing running on the server will be a new product I'm launching that has zero users at this point, but which I'm projecting ( hoping 😉 ) will grow to a few hundred thousand in the next 6 months.

      Full specs: 2x Xeon E5-2680 octacore procs, 256 GB RAM, 6x 1TB 850 Pros in a Raid 10, probably 4x 300G Seagate SAS 10k drives from the original purchase in a 2nd Raid 10.

      If it influences the decision much, I'm going to be running a full web app load on it, IIS, MySQL, and a Java-based app server.

      Thanks!
