Hi,
we are considering a SC4020 all flash array. We got a quote with 6x 1.6TB WI and 12x 3.8TB RI TLC. They told us, that the tier 1 should be sized to hold about 12 days of writing data.
What I understand in the white paper "Flash-optimized Data Progression" is, that beginning with SC OS 6.4 the data will be moved to SSD RI tier after every replay taken. So if we take a replay every 4 hours, we do not need such a large tier 1 with WI SSD. Is this correct?
And a second question: We got also a quote about a single tier SC4020 with RI SSD only (24x 1.9TB), which fits better in our budget. Is there a reasonable maximum size of daily data to be written?
Thanks!
