A customer application generates 2 GB/s writes The outage is under two hours. What capacity must be allowed for the journal?
Answer(s): B
To calculate the required journal capacity, we need to consider the maximum cumulative writes that might occur during an outage. The calculation is based on the application's write bandwidth and the duration of the supported outage. For an application generating 2 GB/s of writes, using a 2-hour outage (which is 7200 seconds), the journal capacity reservation needed is:Journal Capacity=Write Bandwidth×Outage DurationJournal Capacity=2 GB/s×7200 s=14400 GBHowever, since the question specifies that the outage is under two hours, we use the minimum outage allowance of 1 hour for the calculation, which is 3600 seconds. Therefore, the correct calculation is:Journal Capacity=2 GB/s×3600 s=7200 GBBut considering the recommendation to use three hours in the calculations for safety, the needed capacity would be approximately 10.547 TB, which is roughly 10.800 GB12. Hence, the verified answer is 10.800 GB.
What is the maximum number of SDSs per protection domain of the PowerFlex rack?
The maximum number of Storage Data Servers (SDSs) per protection domain in a PowerFlex rack is 1283. This is specified in the PowerFlex specification sheet and ensures that each protection domain can provide data protection for a significant number of SDSs, allowing for scalability and resilience within the PowerFlex infrastructure.
An administrator is creating a NAS server with a Standalone Windows server. Creation of trie NAS server fails What is the cause of the failure?
Answer(s): A
The creation of a NAS server requires a dedicated storage pool. If a storage pool specifically for NAS has not been created, the NAS server creation will fail. This is because the NAS server needs to allocate space from a storage pool to store the file system data. Without a designated storage pool, the NAS server cannot be configured properly.The other options, while important for the operation and integration of a NAS server, are not directly related to the creation process itself. For instance, using the same VLAN as block storage networks (Option B) may lead to network conflicts, but it would not prevent the creation of the NAS server. Similarly, not defining DNS in the NAS server creation wizard (Option C) could cause resolution issues later on, but it is not a prerequisite for the creation of the NAS server. Lastly, while adding FSN to the cluster (Option D) is a necessary step for enabling file system services, it is not the cause of the NAS server creation failure in this context.Therefore, the correct answer is A. A Storage Pool for NAS has not been created, as it is a fundamental requirement for the NAS server creation process in a PowerFlex environment.
What is the default value of paths per volume when adding an NVMe host?
The default value of paths per volume when adding an NVMe host to a PowerFlex system is 8. This setting is relevant for the configuration of multipathing, which is a method used to provide redundancy and increase availability for storage environments. When you add an NVMe host, the system allows up to 8 paths per volume to be configured by default. This is particularly important in VMware ESXi environments, where multipathing can be configured to handle failover and load balancing of storage traffic.The reference for this information is found in the Dell PowerFlex specification sheet, which outlines the maximum paths in the multipathing driver per volume as 8 for ESXi 7.0u31. This document provides detailed specifications and configurations for the PowerFlex system, ensuring that the information is aligned with Dell's official documentation and design guidelines for PowerFlex systems.
