Sequential Stripe on Recent CS

Hello Nimble Guys,

On previous system, Sequential Stripe was 4,5MB. Is it correct ?

Now, Sequential Stripe is 18MB.

Someone can explain me why ?

Regards.

I believe the Stripe size now is 9MB on Adaptive Flash and 10MB on All-Flash.  This is due to the following:

Triple Parity RAID -

On the latest Adaptive Flash Systems, the disk layout is 18+3 for HDD.  512k/disk on 18 disks = 9MB

On the All-Flash Systems, the disk layout is effectively 20+3+1.  512k/disk on 20 disks = 10MB

Make sense?  Let me know if I can answer anything more.
