  • 🔷Why can't I make a new post here in "The Marketplace"? 🤔

    All registered users can reply to other members' posts here in the Marketplace, to respond as potential buyer or ask questions of the seller.
    However, only members who have paid to become "Premium" members or "Patrons" can make a new "for sale" post here in Marketplace.

    Premium memberships can be purchased for as little as $10... a very reasonable fee in order to sell equipment here, far lower than the seller's fee would be on eBay or Audiogon or other sites. Our site doesn't sell ads or sell user's information. This small fee is the only source of funds for the site to offset the costs it takes to run the forum.

    For more information on purchasing a Premium or Patron membership, please see the Account Upgrades section of your user profile.

FOR SALE: 1U and 5U system with K5000 Player

I have a 1U with 4 1tb drives and a 5U system with 8 750gb drives of which 3 of the drives are new. Both systems are full. I'm upgrading to a 3U system. Not sure how to price the package. I'm open to reasonable offers.
 
curious why you didn't use the 5u-to-3u upgrade program? did you work out the numbers and find that the upgrade (with the FREE 2TB replacement discs) would have been MORE expensive than selling your old servers and buying a new 3u?
 
The first server you trade in is a decent value, but subsequent ones are not so good.

For example, if you have 2.1TB on an old server, you get 4 x 2TB drives in a 3U server (because you get the parity drive and hot spare as well as the data drives)

If you had 4TB on a second server, it would only get you 2 x 2TB drives.

Interesting... hadn't thought of that. In fact, I wasn't aware that separate servers share parity and hot-spare space. Had assumed each chassis needs its own.

Brings up a question - had you segmented your Kaleidescape servers into two different Groups in your admin panel, (which I believe gets you two independent movie libraries), would that cause each server to now act completely independently, and therefore establish (or need) its own parity data and (after an upgrade) its own hot-spare? Or do different servers (even in different groups) share parity data across servers and only need a single hot spare across servers?

If segmenting them into groups creates the need for 2nd hot-spare drive, then doing so (assuming you'd keep the segmentation on the two new 3U servers), would have gotten you an extra 1 (2?) drives in an upgrade. (not that I'm proposing gaming their generous system this way, but it would support the argument they should treat every server the same way in calculating the disks they give you in an upgrade).

Each 3U Server requires it's own Hot Spare and RAID.

The reason the second server in a trade in wouldn't be as valuable is because it is unlikely one would upgrade from a 5U and a 1U into TWO 3U servers.

Even if you could, it would be very unwise to spread parity across multiple servers.
 
Close call here to do the Trade-Up or sell your retired stuff outright. By my calculation the Trade-Up option would have resulted in 7 FREE 2TB drives, that's 10TB for available storage. Either way, make sure you get a good replication before you part with the old chassis(s) and drives. God speed, Kevin.
