Since there is a thriving market for these low-end NAS boxes, it can be surmised that at the low end this is not an issue. If one looks at a lot of the QNAP, Synology, and Drobo systems that hold up to six drives, a lot of them use the Atom CPU and therefore forego ECC compatibility. Only non-ECC memory can be used with the platform which is a big consideration for a lot of business users. Maximum RAM is limited to 4GB, dictated by the maximum support of the Atom. There are a few restrictions on memory compatibility on the Atom platform. I still have not found another Atom platform with this option. One can order the boards without management features (look for non-F versions), but for remote management capabilities, this rocks. IPMI 2.0 and KVM-over-IP are really great features. Onboard USB port allows for things like adding a USB drive internal to the chassis for OSes like unRAID and FreeNAS where the OS runs off of a USB drive and the SATA ports can be used for storage.ĥ. Even if one only needs a single core Atom today, it is likely most other use cases will require more computational power and at least a second core.Ĥ. Adding more or less double the performance for a few dollars and slightly higher max power consumption is a good trade-off. Dual onboard Intel NICs provide superior compatibilityģ. Six onboard SATA ports on an Intel controller (most Atom boards rely upon the Atom’s NM10 controller which only supports 2 SATA channels.Ģ. When it is available, I would opt for the D525 and DDR3 DRAM just for the slight speed increase. This build will be focused on the standard mITX size D510 version because the D525 version I have not been able to pick up in the channel yet. Watch out for the non-mITX versions as they are slightly larger than the standard mITX form factor. Supermicro X7SPA-HF (either D510 or D525). Platform 1 is going to be very simple consisting of three items: It will be assumed that these systems are only running one operating system in a bare metal installation (i.e. Unlike the higher-end and mid-range builds, this guide will optimize for cost of initial purchase as well as power consumption. The purpose of this guide is to provide a solution for a system with 2-6 drives which is more robust than a simple 1-2 drive NAS system sold by many vendors. A lot of comments have been logged asking for an entry/ low-end storage DIY guide.
