Which characteristic of OLTP workloads needs to be considered when optimizing OLTP workloads on the SC
A customer has an 8 TB database. Half of the data is hot with very frequent access. The other half of the data
is older, infrequently used cold data. The customer buys (12) 800 GB SLC Solid State Drives, and puts them in
a new disk folder called “Database”. The customer then creates volumes for this database in the Database disk
folder using the recommended storage profile.
After this database has been running for 1 month, the Statistics tab for the database volumes shows 100% of
the space is on Tier 1. The customer expected that half of the data would be on Tier 1 and the rest moved to
What is the problem?
Regardless of the redundancy type selected, which three RAID types are supported by Dell Storage Center?
A site has multiple storage administrators. Some administrators need to be limited to manage only specific
volumes. The administrator should be able to create and present volumes within the administrator’s area.
Those administrators should NOT be able to see any other volumes created in the Storage Center.
How should the deployment engineer accomplish this task?
A volume containing video files 1-10 GB in size uses the default Daily replay profile. This volume needs to be
replicated. The customer needs to use Asynchronous replication and have changes to this volume sent to the
DR site throughout the day. The volume should appear in the same volume folder on the DR system as it does
on the Production system.
Which two replication settings should be enabled in the create replication wizard to meet the customer needs?
An engineer has installed a system as follows:
Tier 1: WI SSD drives
Tier 2: RI SSD drives
Tier 3: 7K drives
All volumes are set to use the recommended storage profile.
What is the purpose of a Space Management Replay in the SC?
The deployment engineer runs all of the commands to initialize the system and reboot the controller. The
engineer then tries to log in several times as Admin/mmm before the setup wizard runs. This login fails.
Why is the user Admin/mmm unable to log in?
Refer to the exhibit.
A deployment engineer is setting up SC4020. The engineer turns on the system. Both controllers initialize to
SafeMode and are ready for configuration. The engineer plugs serial cable into first controller and types
“platform prejoin show”. The output is as shown.
What are two reasons that the deployment will fail if the engineer continues configuring this controller? (Choose
In a dual-controller SC8000 system, how are the Licensed controller and the Leader/Peer controllers related?
