A Dell PowerStore protection policy contains two snapshot rules and one replication rule Which storage resources will run only the snapshot rules?
A Dell PowerStore protection policy contains two snapshot rules and one replication rule, and it applies to specific storage resources such as volumes and volume groups. These resources will run only the snapshot rules, not the replication rule. A snapshot rule allows you to create point-in-time copies of the data, which can be used to recover data in case of data loss or corruption. Snapshot rules are applied to specific volumes or volume groups, and only these resources will be backed up with the snapshot. A replication rule allows you to replicate data to a remote site for disaster recovery or data protection. Replication rules are applied to different resources such as Virtual Machines, File Servers, File Systems, etc. In this case, the snapshot rules will be applied to Volumes and Volume Groups, and the replication rule will be applied to other resources such as Virtual Machines, File Servers, File Systems.
From which storage platforms does a migration import data to a Dell PowerStore cluster?
A migration import allows data to be transferred from an existing storage platform to a Dell PowerStore cluster. The platforms that support migration import to a Dell PowerStore cluster include Unity, VNX2, Dell EqualLogic PS series and Dell Compellent SC Series. These platforms are EMC storage systems, which are now owned by Dell Technologies.
When a remove replication operation is performed on a Dell EMC PowerStore array, what happens to the destination storage resource?
"Removing a replication session is initiated on the source system by removing the protection policy from the Volume or Volume Group on the source system. Removing the protection policy from a storage resource results in the following: * The destination storage resource stays in read-only mode."
What is the purpose of the NVMe NVRAM drives in a Dell EMC PowerStore 1000 array?
The base enclosure is an all-NVMe platform, capable of supporting NVMe SSD, NVMe SCM, and NVMe NVRAM drives. You can populate slots 0 through 20 with NVMe SSD or NVMe SCM drives. Slots 21 through 24 are reserved for NVMe NVRAM drives which serve as additional system write caching. PowerStore 1000 and PowerStore 3000 models contain two NVMe NVRAM drives in slots 23 and 24.
How are vVol datastores mounted in Dell EMC PowerStore storage during the creation of vVol datastores in the vSphere environment shared by ESXi hosts?
A storage container is used to present vVol storage from a PowerStore cluster to vSphere. vSphere mounts the storage container as a vVol datastore and makes it available for VM storage. When a PowerStore cluster is used to provide VM storage, user VMs should be provisioned on the vVol datastores. The default storage container is mounted automatically on the nodes of the cluster.
A storage administrator wants to do a tech refresh from a legacy EQL system to a new Dell EMC SC Series array. What is needed to correctly size the new array?
(1.9 Sizing an SC Series array for performance requirements - pag.9)
A customer has a Dell EMC SC9000 array with six SC420 enclosures running SCOS 7.3. The enclosure configuration is as follows:
What is recommended as a general guideline for making spare drive assignments?
"SCOS 7.3, Distributed Sparing: eliminates the need for dedicated spares by giving customers the option to distribute sparing capacity across all drives in the array."
How many hierarchical snapshots are supported by Dell EMC Unity?
What is the minimum recommended amount of Flash capacity in a Dell EMC Unity 480 Hybrid pool?
The minimum recommended Flash capacity is at least 5% of the pool capacity.
A Dell PowerStore 9000X came online after being initially configured seven days ago. The manager Ul shows capacity but no forecasting metrics
Why are forecasting metrics not being displayed?
Capacity forecasting requires the installation of a special license to display capacity forecasting metrics. If the license is not installed, then the forecasting metrics will not be displayed.
A Dell EMC PowerStore customer plans to migrate storage volumes across appliances within a cluster. They want to use minimal effort to ensure that the appliance avoids reaching full capacity.
Which method is recommended?
Assisted migration - In the background, the system periodically monitors storage resource utilization across the appliances. Migration recommendations are generated based on factors such as drive wear, appliance capacity, and health. If you accept a migration recommendation, a migration session gets automatically created.
What are the two biggest factors that determine IOPS when using SSDs in a Dell EMC SC Series array?
The reason there is such a large range in the number of IOPS delivered by SSDs is the IOPS are truly dependent on the type of traffic the SC Series was designed to handle. The two biggest factors that will determine IOPS in an SSD environment are block size of the application and overall throughput.
Which Dell EMC tool uses an HTML5 interface and best practices to predict storage performance?
Which path of the size tool for Dell Unity XT uses predefined configurations that are based on array model capacity points, random workloads RAID type and drive type?
The System Designer path of the size tool for Dell Unity XT uses predefined configurations that are based on array model capacity points, random workloads RAID type and drive type. This path is designed to make the sizing process quick and easy, providing recommended configurations that are optimized for specific array models and workloads. It allows the user to select an array model, and then it will provide a set of predefined configurations that meet the desired capacity, performance, and availability requirements.
A solutions architect must present two different Dell PowerStore options to a customer Both options must contain 90 TB raw in the smallest drive configuration possible A 3000T and a 9000T are the two models requested The customer wants to know the minimum drive count necessary to perform a capacity upgrade
Which solution should be recommended?
This option provides the smallest drive configuration possible for both the 3000T and 9000T models, and allows for single drive upgrades, which is more flexible for the customer.
What is a consideration when sizing a Dell EMC SC Series system for capacity?
(Input/Output Operations Per Second) is a key consideration when sizing a Dell EMC SC Series system for capacity. IOPS is a measure of the performance of a storage system, and a higher number of IOPS generally indicates better performance. Other factors to consider would be the number of disk drives, RAID configuration, and storage capacity required for the specific use case.
Which Dell EMC Unity OE 5.0 enhancements improve asynchronous replication?
Dell EMC Unity OE version 5.0, asynchronously replicated file resources can also be configured in advanced replication topologies. This allows for configurations such as fan-out and cascading replication at the granularity of a NAS Server and its associated file resources.
