Budget Conscious & Safe build out for 50 Users / 100TB

Currently I have three HP D2600 filled with 600GB SAS drives in raid 6 that is used for an imaging services bureau (18 million images / 18TB / accessed by 8 people).  I’m in the process of adding a fourth D2600 and 12 more 600GB SAS drives.

 

My primary capacity is a developer but I also handle all of the networking / infrastructure.  I’m hoping someone with more knowledge can help me with.

 

Question 1 - These D2600 are rated for up to daisy 4X 2600’s X 4 ext SAS on the P822 controller = 192 drives.  I’m getting nervous having 48 drives on one array.  

 

At what point do I hit “Too many drives” for a raid 6 (or RAID 60) array?  I have Array controller, 3 enclosures, 6 ext SAS connections as failure points.  Continuing to grow extends my points of failure - can someone help me gauge if these things were really intended to have 100+ drives on a single array?

 

Question 2 - Tentatively my next build out I need to support up to 100TB, 100 mil files & 50 employees .  The build out needs to start slow (immediate needs) & grow over time. I see three options (keeping things in the HP fold)

A - Keep adding to existing array with 600GB SAS 3.5 drives.

 

B - Use D2700 / 1.2GB 2.5 10K SCSI drives which will cut down on my enclosures / ext SAS connectors (less likely to fail?).

 

C - Get two MDS600 - two boxes to put everything in.  (Max 74TB high speed SAS w Raid 60).

 

But for whatever reason NONE of those options feel safe to me.  Maybe it’s because I don’t have experience running 100+ drives in a single array?  Or it’s actually a horrible idea?

 

Question 3 - Prior to an upgrade - the imaging department ran a Raid 6 Array using 25 7,200 RPM hard drives in an EMD Netstore (company no longer exists).  It supported up to 15 users doing imaging work.

 

Can I go back to 7,200 RPM HP Sata drives and support 50 people hitting the array?

P.S. Budget is important.

Hello,

New "Chalk Talk" video from HPE's Calvin Zito posted only last week might give you a few more options than what you've got above.

Five minute intro to new products in the Entry Level Storage family. Worth a look.

Cheers
