Subject Migrating to LCS : Disk Size recommendation clashes
Date Thu, 13 Apr 2017 12:23:44 GMT
Hi All,

We are in process of migrating from STCS to LCS and was just doing few reads on line . Below
is the excerpt from Datastax recommendation on data size  :

Also there is one more recommendation where it hints down to disk size can be limited to 10
TB (worst case) . Below is also excerpt also :

So are there any restrictions/scenarios due to which 600GB is the preferred one in LCS.

Thanks & Regards
Amit Singh
