Sure, but, there may be a better solution, something all ready out there |
21 |
and it really depends on refining your needs, current and in the future. |
22 |
So lets refine your specifications (centric to your needs + growth) and |
23 |
figure out what and how much you need. Then we can survey the |
24 |
embedded-thingies, that meet your specs, with a bit of room for growth, OK? |

Wow, that's big. What the number and capacity (TB) of |
30 |
your existing hard-drives? |
31 |
|
32 |
How much more storage do you want? Replacing drives with larger |
33 |
capacity, might be all you need to do? |

OK, so we first spec out options, then let you decide. Then you can |
40 |
'bargain shop' for appropriate housing/rack/open chassis, etc. |

embedded are not only small, they can have extended temperature ranges |
47 |
of tolerance, use drastically less power and many other features. If |
48 |
it's purposed hardware, that is only a few things todo, then yes |
49 |
embedded uP (abbrev for microProcessor) are the way to go. Running off |
50 |
of 12VDC, means an old car battery and a connection to your solar panels |
51 |
(assuming you have those) and it's zero on your electric bill. There is |
52 |
usually a vast array of tax and other incentives, particularly with |
53 |
solar in Ag businesses. |

Dale, you are pretty strong with Gentoo Linux, so putting a stripped, |
61 |
purposed, minimized gentoo derivative stack, with far less ebuilds, to |
62 |
work for your operations, is going to be quite fun. On a farm or ranch, |
63 |
there are a myriad of things you can do with embedded boards and |
64 |
gentoo-stripped. You can replace many of those expensive (vendor) |
65 |
systems with embedded boards +sensors +controls codes and lots of wires |
66 |
to do most anything. Let's focus on your NAS for now. |

SATA, was great years ago. Still it makes sense to use, if you already |
73 |
have them. Storage going forward is the process of faster and cheaper |
74 |
and leaving SATA behind, like ide. Still useful, but a power hog. So |
75 |
we'll start out with interfacing your existing SATA drives to the |
76 |
embedded board, and look/decide on options for newer Solid State Data |
77 |
storage options. |

You might not even need many sata ports. usb3 and the upcoming usb4 have |
83 |
tons of bandwidth (date/time). Mechanical Hard drives are on the way |
84 |
out. Too expensive and failure prone. SSd and other types of storage, |
85 |
might be right for you, or a mixture. USB stick memory |
86 |
can be huge, very low power draw and very inexpensive. |
87 |
|
88 |
A hybrid of several types of memory storage may be useful to experiment |
89 |
with. You may want to categorize your long term storage: some accessed |
90 |
often, others maybe once a year? |
91 |
|
92 |
|
93 |
For data storage, long term important stuff, you should employ RAID |
94 |
(1-10). We can get into that later, duplication of important data, via |
95 |
backups or extra storage is a good idea too. Backups are an old |
96 |
technology, but may help, but backups do can get old too and fragmented. |
97 |
For now, lets not worry so much about long term bit integrity, but focus |
98 |
on your next FUN gentoo rig. I'm hoping other join in to so you have |
99 |
more than my prospective on your solution. |

OK, so let's survey some system, you can just purchase |
107 |
with gentoo preinstalled, or a very easy pathway to embedded gentoo. |
108 |
Let's look at a few, have some of the other guys jump in, and find you a |
109 |
solution, to start with. Most will be expandable, and you can figure out |
110 |
the casing, mounting, power and such. |
111 |
|
112 |
At this stage, it mostly a research effort and then deciding your |
113 |
features/price. If you do not have massive bandwitdh requirements, I'm |
114 |
sure we can find you |
115 |
a very cost effective, DC powered solution. |
116 |
|
117 |
Just so you know, I use that fancy $300 OPtima 12vdc charger, and Optima |
118 |
batteries. the charger reconditions most batteries, if they are not |
119 |
beyond saving, even cheap lead-acid batteries. Every Farmer should have |
120 |
one, imho. The Digital 1200 is just awesome. |

If you like, you can read up on blue, red and yellow top versions and |
125 |
their intended duty-cycle. |

Take some time and look at these gentoo embedded boards, before we |
128 |
diverge to other offerings: |

Dale, embedded gentoo is about the most fun thing you'll ever do. A |
141 |
hardware guy like yourself, that is already an accomplish part of the |
142 |
great gentoo community, dude, |
143 |
your going to have a lot of fun, and save money on that farm. So let's |
144 |
get started! |
145 |
|
146 |
Post back and I, or others, will try to answer your questions. Be |
147 |
specific about what you do currently and where you want to end up. |
148 |
|
149 |
Just so you know, imho, (2) of the finest humans and accomplished Gentoo |
150 |
devs are listed in gentoo-embedded. |
151 |
Actually, all the members are just totally awesome humans, so you, my |
152 |
friend, are in for the ride of a lifetime! |
