iSCSI offload is a network option that can be configured to provide the best iSCSI performance on a Dell Unity XT array. This option offloads iSCSI processing to the network adapter card, reducing the load on the host CPU and improving performance. With iSCSI offload enabled, the network adapter card can handle iSCSI processing tasks such as packet segmentation and reassembly, reducing the CPU overhead associated with iSCSI operations. Other options such as using a single VLAN for all traffic, configuring jumbo frames and disabling flow control may also help to improve iSCSI performance but iSCSI offload would provide the best results. It is important to note that configuring jumbo frames could have a positive impact on performance, but it also depends on the network infrastructure and the NICs support for it. Disabling flow control could cause issues on congested networks, so it's important to test it before disabling it.

Dell PowerStore supports a variety of NAS protocols to provide file access to clients. These protocols include:

• SMB (Server Message Block): This protocol is used to provide file and printer sharing on Windows-based systems.
• NFSv3 (Network File System version 3): This is a standard protocol used to provide file access on UNIX-based systems.
• NFSv4 (Network File System version 4): This is the latest version of the NFS protocol and it provides enhanced security and improved performance over previous versions.
• FTP (File Transfer Protocol): This is a standard protocol used to transfer files between computers over a network.
• SFTP (Secure File Transfer Protocol): This is an extension of the FTP protocol that provides secure file transfer using SSH (Secure Shell) encryption.

A node can tolerate a single fan module fault, and the surviving fans increase their speed to compensate for the faulted module. If two fan modules fault within the same node, the node performs a protective thermal shutdown. A protective thermal shutdown gracefully powers off the node, and any resource fails over to the surviving node

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.

The maximum number of data drives that can be put in to a Dell PowerStore 1000T base enclosure is 21. The Dell PowerStore 1000T has a 2U form factor, and it supports a maximum of 21 drives in the base enclosure. The drives can be either SAS or NVMe, and it's important to keep in mind that the maximum capacity of the system depends on the type of drives that are used. It's important to note that the PowerStore 1000T supports up to 2 expansion shelves that can hold an additional 21 drives each, for a maximum of 63 drives in total. Also, the PowerStore 1000T supports up to 4 NVRAM modules that are used to cache metadata and improve performance.

This provides improved security and encryption traffic performance for SMB3 by changing the encryption algorithm from AES-CCM-128 to AESGCM-128. Page 40 :https://www.delltechnologies.com/en-zm/collaterals/unauth/white-papers/products/storage/h15572-dell-emc-unity-nas-capabilities.pdf
