Volume Tests Sample Clauses

Volume Tests. In these tests we attempt to investigate fie size limitations. In many communities, individual files are becoming larger and larger. Already we are seeing individual sizes of the order of a terabyte, and even the norm is approaching tens of gigabytes for these communities. If a storage system or federation layer is unable to archive these larger file sizes then this has an implication for communities in terms of how they will need to store data within EUDAT. Due to the nature of the clients involved it was difficult to exceed 100GB as an input file for most sites. However, at several sites it is known that files of 1Tb or more are already archived. Within the current test infrastructures it is not possible to replicate this file size. However, there are technologies that interface to mass storage systems which do limit the filesize, such as ‘Safety Deposit Box’ which reads the whole file into memory before sending it to storage and hence is limited by the amount of memory available on the host. We have looked at the transfer time to migrate these files in addition to see what impact file size had on transfer rate. These are shown for ‘native’ protocol Figures 16 and 17, and when using iRODS in Figures 18 and 19. 1800 1600 Transfer Time(secs) 1400 1200 1000 800 600 400 200 1 2 5 10 20 50 100 File Size (GB) STFC PNSC GPFS) PNSC (NFS) DKRZ UiO RZG Figure 16: Transfer Time as a Function of File Size (Native Protocol) 900 800 700 Rate (MB/s) 600 500 400 300 200 100 0 File Size (GB) STFC PNSC(GPFS) PNSC(NFS) DKRZ UiO RZG Figure 17: Transfer Rate as a Function of File Size (Native Protocol) From the tests with the native protocol it is clear that transfer rates do not vary significantly with file size, and also the setup at RZG (XFS) and PNSC (with GPFS mounting) performs significantly better than the other storage systems. This may be gown to different configurations at each site, such as some sites using 10GB NIC cards while others are still using 1GB. However, for most sites it is clear that the transfer rate is of the order 80 MB/sec using ‘native’ protocol. 4500 4000 Transfer Rime (secs) 3500 3000 2500 2000 1500 1000 1 2 5 10 20 50 100 File Size (GB) STFC PNSC (GPFS) PNSC (NFS) DKRZ UiO RZG Figure 18: Transfer Time as a Function of File Size( iput protocol) 45 40 35 Rate (MB/s) 30 25 20 15 10 5

  • ACCEPTANCE TESTS 11.1 If the Contract provides acceptance tests for Goods and/or the result of Services after their completion and/or delivery to the Purchaser, the acceptance shall only be considered as definitive when such tests have demonstrated the compliance of the Goods and/or the result of the Services to the requirements in the Contract.

  • Test The outer surface of the lamp lenses shall be subjected once or more than once to the action of the sand jet produced as described above. The jet shall be sprayed almost perpendicular to the surface to be tested. The deterioration shall be checked by means of one or more samples of glass placed as a reference near the lenses to be tested. The mixture shall be sprayed until the variation in the diffusion of light on the sample or samples measured by the method described in Appendix 2, is such that: Δ d = (T5 - T4) / T2 ≤ 0.0250 ± 0.0025 Several reference samples may be used to check that the whole surface to be tested has deteriorated homogeneously.
