QUESTION 150
Exhibit
A European Sports TV network is considering Isilon for their Media Edit Storage for their editing workloads. They are also considering Isilon for near-line media archiving. The network receives XDCAM HD footage which is loaded onto their existing Transcoding Storage platform. New footage that needs to be edited will be transferred from their Transcoding Storage platform to the proposed Media Edit Storage platform at the rate of ten simultaneous XDCAM HD files via FTP. Edited files will be transferred back to the Transcoding Storage platform at the rate of ten simultaneous XDCAM HD files via FTP. The network currently has 15 Final Cut Pro edit stations, 15 Avid edit stations. Proxy software will be used to allow Isilon to act as the storage for the Final Cut Pro and Avid media. Three of those edit stations will be performing content compositing as needed. The network expects 70 hours of new content per week, and 50 hours of edited content per week. They intend to keep the new and edited content on the proposed Media Edit Storage as a performance tier for 30 days. They would like to retain all new and edited footage proposed Media Edit Storage as a near-line tier for two years. In addition to the current workloads, the network expects to implement a new Media Asset Management (MAM) solution and has requested the Isilon cluster be capable of supporting 120 MBps read and 120 MBps write to support the MAM requirements. Refer to the exhibit.
Based on the number of edit stations, and their intended use, what bandwidth requirements should be considered while sizing?
A. Write Performance:
– 70 MBps FTP sequential
– 21 MBps NFS and/or SMB sequential
– 120 MBps NFS and/or SMB random
Read Performance:
– 70 MBps FTP sequential
– 210 MBps NFS and/or SMB sequential
– 120 MBps NFS and/or SMB random
B. Write Performance:
– 550 MBps FTP sequential
– 275 MBps NFS and/or SMB sequential
– 120 MBps NFS and/or SMB random
Read Performance:
– 550 MBps FTP sequential
– 1.6 GBps NFS and/or SMB sequential
– 120 MBps NFS and/or SMB random
C. Write Performance:
– 21 MBps FTP sequential
– 70 MBps NFS and/or SMB sequential
– 120 MBps NFS and/or SMB random
Read Performance:
– 210 MBps FTP sequential
– 70 MBps NFS and/or SMB sequential
– 120 MBps NFS and/or SMB random
D. Write Performance:
– 70 MBps FTP sequential
– 210 MBps NFS and/or SMB sequential
– 120 MBps NFS and/or SMB random
Read Performance:
– 70 MBps FTP sequential
– 21 MBps NFS and/or SMB sequential
– 120 MBps NFS and/or SMB random
