I am currently pricing out some DCS3520's, for OSDs. Word is that the price is going up, but I don't have specifics, yet.
I'm curious, does your real usage show that the 3500 series don't offer enough endurance? Here's one of our DCS3700's after 2.5 years of RBD + a bit of S3: Model Family: Intel 730 and DC S35x0/3610/3700 Series SSDs Device Model: INTEL SSDSC2BA200G3 Firmware Version: 5DV10270 User Capacity: 200,049,647,616 bytes [200 GB] 9 Power_On_Hours 0x0032 100 100 000 Old_age Always - 22580 226 Workld_Media_Wear_Indic 0x0032 100 100 000 Old_age Always - 3471 228 Workload_Minutes 0x0032 100 100 000 Old_age Always - 1354810 232 Available_Reservd_Space 0x0033 099 099 010 Pre-fail Always - 0 233 Media_Wearout_Indicator 0x0032 097 097 000 Old_age Always - 0 241 Host_Writes_32MiB 0x0032 100 100 000 Old_age Always - 8236969 242 Host_Reads_32MiB 0x0032 100 100 000 Old_age Always - 7400 Still loads of endurance left. Anyway, in a couple months we'll start testing the Optane drives. They are small and perhaps ideal journals, or? -- Dan On Wed, May 17, 2017 at 11:12 AM, Nick Fisk <n...@fisk.me.uk> wrote: > Hi All, > > There seems to be a shift in enterprise SSD products to larger less write > intensive products and generally costing more than what > the existing P/S 3600/3700 ranges were.
