Q170. When planning a new cluster using backend leaf-spine topology, what is the maximum number of nodes supported when using two leaf switches and one spine switch?

Q171. Which tool is used to perform a cluster-wide kernel configuration change on an Isilon Gen 6 cluster?

Q172. In OneFS, what is the largest number of disks in a subpool?

Q173. Which directory path is the recommended PowerScale directory structure?

Q174. What do you need to take into consideration when planning a job schedule?

Q175. A customer is interested in adding A100 Backup Accelerator nodes to their Isilon cluster. The customer’s cluster consists of seven S-Series nodes.
What is the recommended number of A100 Backup Accelerators to achieve maximum throughput?

Q176. Your customer has observed a degradation in response time while browsing for media files within the Production Media folder of the Isilon cluster. That directory now contains over five million files. It was confirmed that there are no network or edit station related causes.
What changes to the Isilon cluster will best accelerate the browsing performance?

Q177. A customer is collecting remote sensor data that must be maintained for future legal challenges. The data will rarely be accessed, and the customer wants to have minimum financial investment.
Which PowerScale node should be recommended for this purpose?

Q178. A healthcare services provider is implementing an X-Series cluster. Currently they have approximately 200 customers and they are growing at 30% per year. They have 200 TB of storage utilized.
Health Insurance Portability and Accountability Act (HIPAA) regulations require they keep all patient data for seven (7) years. They would like to keep all genomic sequencing data stored with N+3 protection, not to exceed 75% utilization.
What is the minimum initial configuration you would recommend?

Q179. You have had several discussions with your customer in the processor design industry. They have stated that they want a Scale-Out NAS platform for their design environment.
Their most significant responses were “We have 125 design engineers accessing large diagrams and we need high throughput to support them. Can we also get the highest performance available?
We need to stay ahead of our competitors.” Other areas you discussed were their data retention policies and workflow after the chip design is completed. They plan to archive the design files but the files must stay on line.
What is your initial node recommendation?

Q180. What is the best case performance for Backup Accelerator when backing up to LTO-4 or LTO-5 drives?

Q181. What determines the number of job engine workers assigned to a task?

Q182. A large financial services company requires a capacity expansion for retaining over 2.5 PB of document images as a cold archive.
Which Isilon node series should be recommended?

Q183. A potential customer has a requirement for 4 PB of usable capacity to store media files. Their data center has limited physical space, so efficient use of that space is important. However, the customer is concerned about using 3 TB or larger drives because of rebuild times.
How does an Isilon cluster address this customer’s concern?

Q184. On an eight node Gen 6 cluster, how are files greater than 128 KB protected?

Q185. While considering expanding a current Isilon cluster, what tool or report can be used to investigate current file sizes used on the cluster?

Q186. Refer to the exhibit.

A large hospital chain has approached you to redesign their storage infrastructure. The head of IT believes their requirement is for 100 TB of RAW capacity.
They want to consolidate their PACS, file shares and home directories onto one cluster and require very fast enumeration of the directories. The following are the notes from meetings with the department heads.
Which is the best cluster configuration that meets the customer’s requirements?

Q187. Where are file system changes first stored?

Q188. An architect is designing a solution for a customer that is replicating data between two data centers
15 km apart from each other. The customer requires point-in-time protection.
What is possible in a SyncIQ policy?

Q189. Which process is used to protect file system structures against corruption through 32-bit CRC checksums?

Q190. You are sizing an Isilon Gen 6 cluster for a small organization that is concerned about the availability of the journal during an extended power outage.
What is a consideration when sizing?

Q191. How are clients, L1 cache, L2 cache, and disks interconnected?
