A customer wants to implement virtual provisioning on a new VMAX array and is concerned about efficient use of available storage and application performance.
The VMAX environment will have file system, database and document repository hosts. The customer reports the system hosts append data to the file system, the database hosts use auto- extend and the document repository hosts have low performance and growth requirements. How should you recommend the host storage be provisioned on the VMAX array?
A. File system storage on traditionally provisioned volumes; database and document repository storage on thin volumes.
B. File system, database and document repository storage on thin volumes.
C. File system and database storage on thin volumes; document repository storage on traditionally provisioned volumes.
D. File system, database and document repository storage on traditionally provisioned volumes.
An SRDF/S customer has implemented FAST VP at R1 and R2 sites. What will happen to a thin R2 device when a thin R1 device extent is promoted?
A. The corresponding extent on the R2 device will be promoted as long as there is storage space available in the higher tier
B. Nothing. Promotions on the source do not affect the target
C. The corresponding extent on the R2 device will be promoted simultaneously only if the FAST VP policy allows it
D. The corresponding extent on the R2 device will be promoted if the target Symmetrix is not too busy
A Symmetrix VMAX is configured with FAST DP. It contains three tiers of storage:
1.
200 GB RAID 5 (3+1) EFD
2.
300 GB RAID 1 15K RPM Fibre Channel
3.
1 TB RAID 6 (6+2) 7200 RPM SATA The storage administrator would like to charge each department that uses the VMAX for the amount and class of storage they use. Which FAST policy would best lend itself to the chargeback system?
A. Tier 1: 10% Tier 2: 60% Tier 3: 30%
B. Tier 1: 50% Tier 2: 50% Tier 3: 50%
C. Tier 1: 20% Tier 2: 40% Tier 3: 50%
D. Tier 1: 100% Tier 2: 100% Tier 3: 100%
What is considered to be a thin unfriendly environment?
A. an environment that makes use of filesystems that append data instead of re-using free space.
B. an environment that contains databases that make use of the auto-extend capability.
C. an environment that is used for media and document repositories.
D. an environment that is used by Test Development and Quality Assurance.
What can be used to monitor free space in a thin pool on a Symmetrix VMAX?
A. The Control Center Host Agent.
B. The Replication Manager IRCCD daemon.
C. Tier Advisor.
D. The event daemon storeventd.
What is the size of a thin device extent in a Symmetrix VMAX?
A. 768 KB
B. 512 KB
C. 64 KB
D. 1024 KB
What are the main components that make up a virtual provisioning environment?
A. TDEVs, TDATs and a Thin Pool.
B. DRVs, CDEVs and a storage pool.
C. Striped Metas, VDEVs and a Thin Pool.
D. Masking Views, VDEVs and BCVs.
What is one of the benefits of virtual provisioning?
A. eliminates the need for an auto-provisioned port group.
B. wide striping distributes I/O across physical disks.
C. provides newer commands such as the symcfg command.
D. reduces return on investment.
