Need a solution for 60TB+
What I want to do is eventually have about 60TB or more of DVD and BluRay ISO images online for my media server.
Currently Im using a ReadyNAS Pro 6 and a ReadyNAS Ultra 6 each loaded with 3TB drives They are at full capacity now
And I figure 60TB will give me the headroom I will need for my current plans.
So essentially I need a platform that will handle 36TB initially and be able to expand to about 60TB or more.
Not sure if the 5200 series will give me the functionality I need and I may be missing something simpler or more
cost effective.
So any input would be appreciated.

- An RN516 + 3 EDA500 extenders can reach 84 TB with 4 TB drives. If you are using XRAID2 with single redundancy, it would go down to 68TB (4 volumes, 6x4TB, 5x4TB, 5x4TB, 5x4TB). This would be cheaper than ReadyDATA 5200 + EDA4000 extenders (and probably quieter).
Also, note that 5 TB (and even 6 TB) drives are beginning to appear, which will increase these capacities. Though the 6 TB drives are extremely expensive.
Do you really need this on a single NAS? Deploying multiple NAS might be more flexible. - Well NEED no...dont NEED a single NAS but Seeing as how all the images are related and it would be a pain trying to balance the content across multiple platforms....The appeal of one large storage area seems very nice.
Right now I have the load spread across a ReadyNAS 314, RN Pro and an RN Ultra 6 Pro...and this is why I was looking for a single storage pool solution. - You would still have to spread the storage across multiple volume. The more disks in the RAID array, the more fragile it is.

of course that does not include OS, you would have to determine best os and raid format(s) to use
The site to purchase it is here: http://45drives.com/products/direct-wired-standard.php About $5400 US for one unit with non-redundant power supply (and it does come with the OS installed). Though I don't see any info about the OS.TeknoJnky wrote: http://blog.backblaze.com/category/storage-pod/

RAID format is an interesting question for 45 drives. Here's what backblaze does:Each Storage Pod of 45 drives is logically divided into 3 RAID arrays utilizing RAID 6 for redundancy. Given the physical layout of a Storage Pod of 3 rows of 15 drives each, you might assume each row is a RAID array, but it’s not. In each row, every 3rd drive is a member of the same RAID array. This is done to spread a given array across all 9 of the backplanes the drives plug into. It also minimizes the impact on a given array if a backplane fails.
So they would allocate 6 drives for redundancy, giving you 156 TB if you used 45x4TB. And they'd provide 3 volumes.- For that type of capacity you may like to look at general server equipment and then build out a Linux (or Windows) server that can operate as a large scale file server. One hardware vendor that does some very nice cases for large disk arrays is SuperMicro as can be seen from this
http://www.supermicro.nl/products/syste ... R72L2K.cfm
Its design supports up to 72 drives across 3 controllers.
Just find a reseller that can add disks, memory and processor(s) that meet your requirements, which will very much depend on the type of file system deployed. - Also keep in mind that this class of equipment is usually very noisy - and the noise level is not spec'd since it isn't intended for home installations. So you should make sure you have a location for it where the noise doesn't matter.

For a supermicro solution think jet engine as a 72 drive system would be in the 1.5-2KW heat output range :)- The unit is in a nice cool dry corner of the basement next to my 24 port Gigabit switch..the house is wired with cat5e or cat 6 cant remember which
This is really just an extravagance for me, Im filling the space with riped DVD's and BluRays I own....the Television shows with several seasons of content really take up space..especially the ones in BluRay. So I rip them all to ISO format and then pack the Physical media away in nice clean containers. - Those Storage Pods look nice but are probably much more than I need.
Maybe EMC will have a clearance sale and Ill pick up one of their old SAN units ;)
