Information about the Storage capacity of the sample is presented in Table 18.
Please present information in relation to the TB of storage devices available in the NGI
site/ HPC Centre at the end of year 2011.
Answer Options Min Max Average Median
Disk Storage in TB as on 31/12/2011 3 13,070 1,207 333
Tape Storage in TB as on 31/12/2011 72 12 7,350 1,903 980
Table 18: Storage information
Information about the acquisition costs of both hardware and storage of the sample is presented in Table 19.
Please present the average acquisition (i.e. purchase) cost per logical CPU and the average cost per TB
acquisition in 2011. In case you have no data for 2011 please use approximations based on the most recent
procurements or budget data. Note: Please do not include any hardware support contract costs or software costs
in the values presented below
Answer Options Min Max Average Median
Cost per logical CPU in € in 2011 80 800 275 218
Cost per TB/ Tapes in € in 2011 37 170 88 78
Cost per TB/ Disks in € in 2011 80 3,000 493 270
Table 19: Acquisition cost of logical CPU and storage information
The cost per logical CPU and the cost per TB exhibit significant differences. As one respondent commented these
costs are rather dependent on the choice of compute/storage technology. It can be easily seen that the number of
answers is this question are less that the total sample. According to informal discussions the disclosure of
procurement information related to prices is considered sensitive data and therefore some respondents refrained
from presenting their case 73 . The limited number of responses in relation to cost per TB for tapes is probably
related to the fact that not all respondents use tapes as a storage medium.
Depreciation rates
The average useful lives for hardware and software are presented in Table 20. Depreciation rate can be calculated
accordingly.
72 We have included in descriptive only sites have non zero tape storage.
73 We expanded our information set regarding hardware (computing and storage) procurement prices by getting information
from the EGI compendium study. This type of information was used for cross-­‐checking purposes. The median cost per logical
CPU in EGI compendium was € 192 (6 responses) while the cost per TB € 373.
