You are conducting an analysis of a Celerra system to migrate the data to a new VNX Unified storage system. You want to collect statistical information about CIFS file system activity.
Which "server_stats" statistic type would you use to get the desired information?
Which "server_stats" statistic type would you use to get the desired information?
정답: D
An application generates 1000 random 16 KiB IOPS with a R/W ratio of 4:1. An asynchronous mirror is started on the application LUN. The update cycle is configured to be 20 minutes, and updates take 6 minutes to complete. Assume that the data rate is constant.
What is the minimum space that should be configured for the Reserved LUN Pool on the secondary VNX?

정답: C
Your customer is designing a Proof of Concept with SQL Server attached to a VNX. The storage design includes seven LUNs on a RAID Group. The system is generally very heavily loaded, with a particularly high load on the cache. This is a very carefully controlled environment and your customer has asked for assistance in planning the layout of the LUN location on the physical spindles.
Where in the RAID Group would you recommend placing the two heavily used LUNs for a "short-stroked" architecture?

정답: C
Refer to the Exhibit.
An administrator is checking the load on the array. The administrator is trying to determine if this is an acceptable range (between 8370 and 8990 IOPs). Based on the illustration, what can you conclude?

정답: D
A VMware Administrator has received numerous reports from his users about performance degradation. The administrator believes that your storage design on the VNX is the reason for the symptoms.
You ask the administrator for an esxtop analysis of the affected ESXi server. When you examine the report and notice that the value on the Load Average Line is 2.00.
What would you report back to the administrator?

Your customer is reporting less than optimal performance for their online payment processing application. The payment processing application is running on a Windows Server cluster with the back-end Oracle databases running on Oracle Enterprise Linux (OEL). Both the application and database environments have been presented storage from the customer's VNX solution.
Which tool is best suited to identify performance issues on the application servers?
