A customer has a large ESX server environment they are considering deploying to XtremIO for a VDI implementation. To determine a baseline of the environment, you are proceeding with documenting each server's CPU, NIC, and disk utilization statistics. The customer has provided you with direct CLI access to the servers to conduct this assessment.
Which utility should be used to monitor these performance parameters?
A. esxtop
B. resxtop
C. top
D. iostat
Which level of granularity does XtremIO deduplication run?
A. Variable 8 kB
B. Variable 32 kB
C. Fixed 8 kB
D. Fixed 32 kB
Which operation is performed when an XtremIO Snapshot is created?
A. Pointers to the ancestor metadata are created for the snapshot
B. Space equal to the size of the ancestor is allocated to the snapshot
C. A reserved space is created for new snapshot data
D. A deduplication pass is immediately run against the snapshot
A customer has a requirement to replicate their VDI to a newly purchased data center located 5 miles away. They require 10-day retention at each site and a continuous replication RPO. However, they want to have the same storage platform at each site. They have a limited budget but need to meet their requirements.
Which solution should be recommended to the customer?
A. XtremIO and OpenStack
B. XtremIO with VPLEX and RecoverPoint
C. XtremIO and RecoverPoint
D. XtremIO and MirrorView/A replication
A customer has a workload with the following attributes: Generates 250,000 IOPs 100 TB in logical capacity Read/Write ratio of 1:1 Random workload with 8 kB I/O size Deduplication ratio of 2:1 Compression ratio of 2:1
Which XtremIO solution should be recommended to the customer?
A. 1×40 TB X-Brick
B. 2×10 TB X-Brick
C. 3×20 TB X-Brick
D. 4×10 TB X-Brick
What is considered typical performance for an XtremIO single X-Brick cluster?
A. Small block writes: 200k-250k IOPs. Large block reads: up to 2.5 GB/s
B. Small block writes: 200k-250k IOPs. Large block writes: up to 2.5 GB/s
C. Small block reads: 200k-250k IOPs. Large block writes: up to 2.5 GB/s
D. Small block reads: 200k-250k IOPs. Large block reads: up to 2.5 GB/s
A storage administrator is adding both an XtremIO and third-party storage arrays to their existing infrastructure. The administrator is using ViPR SRM to monitor the environment.
Which requirement is needed to implement this solution?
A. A single third-party Solution Pack is required to manage both storage arrays
B. Each storage needs its own Solution Pack
C. Each storage array requires two Solution Packs; one for monitoring and one for performance
D. A single XtremIO Solution Pack is required to manage both storage arrays
A customer currently uses XtremIO native remote replication with four RPAs and a 1 GB WAN link to asynchronously protect all production data. Management has decided that all data stored on the XtremIO must now be protected at the disaster recovery site by synchronous replication.
How can this be achieved?
A. Set the Link Policy to Synchronous, Dynamic by throughput
B. Purchase four additional RPAs.
C. Set the Link Policy to Synchronous, Dynamic by latency
D. Use a VPLEX splitter
A customer is considering migrating their existing non-EMC storage arrays to an XtremIO array. The current environment consists of 350 servers running VMware ESXi 5.5 with 5000 virtual machines. The customer has various tools in place to monitor performance and collect statistics. On average, their service time is 32 ms and utilization is at 75%. In the past, the customer has had performance issues.
Based on Little's Law, what is the calculated response time on the existing environment?
A. 128 ms
B. 192 ms
C. 256 ms
D. 332 ms
A customer has a group of applications that need storage which can provide low response times. The total I/O requirements are 75,000 IOPs with a 4 kB block size. They will have 500 LUNs and need to keep 30 daily snapshots of each LUN.
What is the smallest XtremIO configuration that will meet their needs?
A. 1 cluster with 2 X-Bricks
B. 1 cluster with 4 X-Bricks
C. 2 clusters with 1 X-Brick each
D. 2 clusters with 2 X-Bricks each
