Table 3. Dell EMC Unity X80/F Model Comparison

"When positioning the 380 and 380F, keep in mind that they are not NVMe-ready and will not be upgradeable to support NMVe in the future.".

Access-based enumeration is the attribute that must be used at the share level to restrict the share content visibility of a Dell Unity file system based on the access rights. Access-based Enumeration (ABE) is a feature that allows you to hide files and folders from users who do not have the necessary permissions to access them. When ABE is enabled, users only see the files and folders that they have permission to access. This helps to prevent users from accidentally accessing data that they should not have access to, and it helps to maintain the security and integrity of the data on the file system.

The embedded module in a Dell Unity XT 480F system provides management functionality for the system, such as control of the storage array, monitoring of system health and performance, and management of storage resources. This embedded module allows you to manage the system through an intuitive web-based interface or via command-line interface.

When using NAS Server Mobility to move a NAS server from SPA to SPB on a Dell Unity system, an administrator must be aware that any replication sessions must be in a paused state before starting the move. This means that any data replication sessions that are configured for the NAS server must be temporarily stopped to avoid data inconsistencies or data loss during the move. Once the move is complete, the replication sessions can be resumed, and data replication will continue as normal. NAS Server Mobility is still supported by Dell Unity, so it's not a concern of the move. The system does not need to be in service mode to complete the move, and the DNS configuration won't be lost after the move, the administrator should make sure that the DNS entries for the NAS server are updated to reflect the new location.

In this scenario, the customer wants to test their disaster recovery plan and wants all applications to failover to the disaster recovery site. To accomplish this, the technical architect should use the planned failover option from the source site, the primary site. This will allow the customer to test their disaster recovery plan and ensure that all applications can be successfully failed over to the disaster recovery site. It's important to note that if the customer wants to failover to the disaster recovery site for maintenance and after that fail back to the primary site, the planned failover should be run from the target site.

Synchronous replication will provide a zero RPO as all data is written to both the primary and secondary storage at the same time, which means any data written to the primary storage will be instantly available on the secondary storage. This configuration will ensure that the data is protected against system outage, and in case of any failure, the recovery time will be a maximum of 15 minutes as the data is already replicated to the secondary site.

An install of the PowerStore ImportKIT is required on the hosts to support import to PowerStore.

Deduplication uses algorithms to analyze, perform pattern detection, and attempts to store only a single instance of data. In general deduplication can work at the block, bit-level, or file level. In PowerStore, deduplication works at the block level at 4 KB granularity.

Dell EMC Flash Storage Efficiency Guarantee Dell EMC promises our flash arrays will provide a logical usable capacity at least four times the usable physical capacity of your purchased drives —or we’ll give you more drives at no charge.https://www.delltechnologies.com/en-us/blog/dell-emc-flash-storage-efficiency/

Both Dell PowerStore T and Dell PowerStore X support the 10 GbE BaseT optional I/O module card type. This card provides 10 Gbps Ethernet connectivity and can be used to connect the storage array to a network. The other options are not supported by both models. 25 GbE and 32 Gb Fibre Channel are generally faster and used for high-performance systems, while 8 Gb Fibre Channel is an older standard, and not supported by Dell PowerStore T and Dell PowerStore X.

A performance assessment tool is used to evaluate the performance of storage systems and provide statistics that can be used to identify and troubleshoot performance issues. One of the benefits of using a performance assessment tool is that it provides automated performance statistics in chart and table format, making it easy to understand performance metrics and identify any potential issues. This allows the user to quickly identify and address any bottlenecks in the system, and make adjustments to improve performance.
