(This config is absolutely begging for ZFS, but I have a haunting feeling that something janky is afoot upstack.)  I would also be curious as to the specific nature of failures that have been seen with the deployed architecture.  Have the concerns from three years ago proven to be alarmist or prescient?&lt;p&gt;That said:  I think it&apos;s very valuable to get configs like this out there for public discussion -- and I think it might be inspiring us (Joyent) to similarly publicly discuss our own high density storage config...</text><parent_chain></parent_chain></comment><story><title>180TB of Good Vibrations – Storage Pod 3.0</title><url>http://blog.backblaze.com/2013/02/20/180tb-of-good-vibrations-storage-pod-3-0/</url></story>

I used to work in the storage industry and got to play with (what is now) NetApp high-density setups [1].  60 drives in a 4U setup, compared to 45 drives in Storage Pod in the same 4U.  But I&apos;m guessing the cost is where Storage Pod really wins out.  NetApp gear, even as a JBOD, is really expensive.&lt;p&gt;The NetApp box has same type of padding for all the drives, but they are much easier to access (pull out trays are stable and easy to use).&lt;p&gt;Fun issues I saw with the NetApp box (at least 3 years ago): fully loaded with drives, it went over the weight limit that Fedex or UPS would ship with standard shipping.  It required freight shipping to ship a single, full-loaded, E5400.&lt;p&gt;[1] &lt;a href=&quot;http://www.netapp.com/us/products/storage-systems/e5400/&quot; rel=&quot;nofollow&quot;&gt;http://www.netapp.com/us/products/storage-systems/e5400/&lt;/a&gt;</text><parent_chain></parent_chain></comment><story><title>180TB of Good Vibrations – Storage Pod 3.0</title><url>http://blog.backblaze.com/2013/02/20/180tb-of-good-vibrations-storage-pod-3-0/</url></story>
