Dell PowerStore 1000T supports the addition of a maximum of one expansion enclosure when it has 10 SCM drives in the base enclosure. An expansion enclosure can be added to the base enclosure and allows the system to support additional drives and increase storage capacity.

"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.".

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.

The Skylake CPU family is a 6th generation Intel processor, which provides higher performance and improved energy efficiency compared to its predecessors.

An SP hardware fault initiates an automatic NAS server failover to the peer SP in Dell Unity systems. This ensures that the NAS services remain available in case of hardware failure in one of the Storage Processors (SPs). The failover process is automatic and transparent to the hosts accessing the data, and it helps to maintain the high availability of the NAS services.

Dell Unity XT's Host I/O limits feature allows you to set limits on IOPS for individual hosts connected over iSCSI. This can be used to restrict the test/dev hosts to a maximum of 5000 IOPS
