- Units in TB. Original space at the units
- Codes: S -> Flexbuff at the station. J - > Flexbuff at JIVE correlator
- (1) Flexbuff size at JIVE is reduced due to using a RAID. In the total and partial sums this is taken into account, but it is not taken into account in the individual numbers per station and year.
- 144 TB -> 101 TB
- 240 TB -> 168 TB
- 288 TB -> 202 TB
- 360 TB -> 252 TB
- Ef uses a Mark6 and modules which can be replaced. Thus more modules can be used if needed. Latest purchase in 2017 is 16 x 10 TB disks.
- The Hh Flexbuff also uses the same RAID set up as JIVE does.
- A standard 36 unit may use 4, 6 or 8 TB disks.
- 4 TB x 36 = 144 TB;
- 6 TB x 36 = 216 TB
- 8 TB x 36 = 288 TB
- Approximate costs:
- 2015: 44 € /TB (from 4 TB NAS disks)
- 2016:
- 2017: 50 €/TB (from 8 TB NAS disks)
- 2018: (March) ~28€/TB (from 10TB Seagate Ironwolf, €281 inclusive VAT in the Netherlands)
- Replacing disks at Flexbuffs:
- Ys replaces 36 x 4 TB disks by 36 x 10 TB disks. 32 x 4 TB disks are used to populate 4 Mark5B packs. 4 x 4TB are recovered by Ys.
- Wb bought 36 (12 in Nov. 2017 and 24 in Mar. 2018) 10TB disks so that JIVE could upgrade FlexBuffs with larger disks.
- Hh replaces 36 x 4 TB disks by 36 x 10 TB disks. All 36 x 4 TB disks are recovered by Hh.
