Current problem is lack of a computer to accept multiple SATA connections.</p> <h3 id="problem-1-sata-connectors">Problem 1: SATA connectors</h3> <p>This can be solved by an HBE card. Although they tend to be quite expensive (250+). One decent model that isn’t that much is the <a href="https://www.amazon.ca/SAS9211-8I-8PORT-Int-Sata-Pcie/dp/B002RL8I7M/ref=sr_1_2?keywords=9211-8i&qid=1586699707&sr=8-2">LSI 9211-8I</a>. This is ideal for future expansion.</p> <p>A cheaper option is a PCIe multi-SATA connector <a href="https://www.amazon.ca/Rivo-Controller-Expansion-Profile-Non-Raid/dp/B0836MKFCR?ref_=ast_slp_dp">like this</a>.</p> <p>Either work, but one is cheaper and the other is more expandable. The 9211-8I uses two SAS ports, which can be expanded indefinetely. SAS supports splitting. SATA can be connected in a 4:1 ratio to SAS connectors with some <a href="https://www.amazon.com/Cable-Matters-Internal-SFF-8087-Breakout/dp/B012BPLYJC">cheap cables</a>.</p> <h3 id="problem-2-drives">Problem 2: Drives</h3> <p>I do not have enough drives to make this work right now. For the setup I want it would require 5 or 6 drives. I will get 4-5 drives worth of space as one drive worth of space is dedicated to “parity”, making you able to:</p> <ol> <li>Verify data integrity. If anything goes wrong with a write, it will be fixed automatically.</li> <li>If <em>one</em> drive dies, the system can stay online with no problem. Two drives and I’m eff-you-see-kay-ed-dee.</li> </ol> <p>My other option is to use two drives worth of space for partiy. This would only have me 3-4 drives of space, but this system can withstand the failure of <em>two</em> drives.</p> <h3 id="problem-3-computer-system">Problem 3: Computer System</h3> <p>I currently have 5 computers.</p> <ol> <li>Celery Stick. An old grey HP laptop with a Braille stickered keyboard. <em>Does not work right now; bad thermal paste job.</em></li> <li>A Dell laptop lent to me by my school during my studies.</li> <li>Houston. A 21-inch 2011 iMac for which the screen does not work under Linux (excep with the <code class="language-plaintext highlighter-rouge">nomodeset</code> kernel option enabled).</li> <li>An Old Toshiba laptop (circa 2010) that I got for $50 to test with OpenBSD (works….sometimes).</li> <li>Main Rig. My main laptop is an ASUS-705 TUF gaming laptop.</li> </ol> <p>None of these have PCIe expansion slots with a case that can handle the new drives.</p> <p>I think it’s reasonable to say that for hard-drives and low-end tower PCs, I will likely have luck on a place like <a href="https://kijiji.ca">Kijiji</a> (Canadian Craigslist).</p> <p>The search continues :)</p> <p>I’m in for a fun ride…. and a few monnies.</p> </article> </main> <hr> <footer> This page is mirrored on <a href="https://beta.tait.tech/2020/04/12/nas1/">beta.tait.tech</a>. </footer> </div> </body> </html>
