質問 # 150
A 6 F800 node Isilon cluster has one subnet with two IP pools with LACP aggregated 10GigE interfaces from all the nodes in the 'Data-Zone' Access Zone. The 'NFS-Pool' with dynamic IP Allocation schema and 'SMBPool' with static IP Allocation schema are being used.
All the Linux clients are accessing Isilon exports using NFSv3 via the 'NFS_Pool'. All the Windows clients are accessing Isilon shares using SMBv3 via the 'SMB_Pool'.
While deploying Isilon, the customer reserves the whole network subnet for Isilon. The customer is facing performance issues with a new workload that is accessing the Isilon via Kerberized NFSv4.
What is recommended when creating a new IP pool for NFSv4 clients?
Response:
- A. Dynamic IP Allocation in the ,Data-Zone, access zone
- B. Static IP Allocation in the ,Data-Zone, access zone
- C. Dynamic IP Allocation in the ,System, access zone
- D. Static IP Allocation in the ,System, access zone
正解：D
質問 # 151
A potential customer requires 4 PB of usable capacity to store media files. The workloads are a combination of streaming video delivery and long term archive of video assets.
There is very little space available in the customer's datacenter, so physical density is very important. The customer is concerned about performance impact and potential data loss when using 3 TB or larger drives.
What Isilon capabilities can address the customer's concerns?
Response:
- A. N+3 and N+4 Protection Levels exceed traditional RAID6 availability.Proactive hot sparing eliminates most drive rebuilds.Endurant Cache reduces the overhead for write operations.
- B. Isilon does not perform rebuilds - data reprotection is typically 2x-3x faster than traditional RAID rebuilds.N+3 and N+4 Protection Levels exceed traditional RAID6 availability.Data redistribution runs faster with more nodes in the cluster.
- C. Isilon nodes have more drives per rack unit so fewer shelves are required.Proactive hot sparing eliminates most drive rebuilds.N+3 and N+4 Protection Levels exceed traditional RAID6 availability.
- D. Isilon does not perform rebuilds - data reprotection is typically 2x-3x faster than traditional RAID rebuilds.Data recovery is consistent, taking the same amount of time regardless of cluster size.Isilon ,short strokes, 4TB drives to reduce rebuild time.
正解：B
