Netapp NS0-593 Exam With Confidence Using Practice Dumps

 According to the NetApp Knowledge Base, adding a second NS224 shelf to an existing stack can cause the first shelf ID to change to the serial number if the cables are not connected properly1. This can also result in a Medium Impact error message: Shelves with both connections via the same SAS path detected2. This situation is not normal for a NetApp AFF A800 system andcan affect performance and availability. The cables should be reconnected according to the SAS cabling rules and concepts for shelves with IOM12/IOM12B modules3 and the controller-to-stack cabling worksheet template for quad-pathed connectivity4. References = Shelves with both connections via the same SAS path detected, Adding a second NS224 shelf, changes first shelf ID to the serial number, SAS cabling rules and concepts - shelves with IOM12/IOM12B modules, Controller-to-stack cabling worksheet template for quad-pathed connectivity.

A B2B type consistency point (CP) occurs when a new CP is triggered before the previous CP is completed, due to the second memory buffer reaching a watermark. This can cause write latency to increase as user write operations are not replied until a write buffer frees up. However, this only affects the aggregate that is undergoing the B2B processing, and not the other aggregates on the same node. Therefore, the performance of the client operations on the data aggregates will not be affected by B2B processing on the root aggregate. References = What is the Back-to-Back (B2B) Consistency Point Scenario?, What are the different Consistency Point types and how are they measured in ONTAP 9?, What are the different Consistency Point types and how are they measured?

= A user quota is a limit on the amount of disk space or the number of files that a user can consume on a volume. A user can be represented by multiple IDs, such as UNIX user ID (UID), Windows user ID (SID), or name mapping ID. A file owned by any of these IDs is subject to the restriction of the user quota. If a user has files in different directories or qtrees within the same volume, all of those files count towards the user’s quota limit. Therefore, if other files within the volume are also owned by the user, they could exceed the user quota and prevent the user from saving more files to their home drive, even if the home drive itself shows minimal data usage. References = How quotas work with users and groups overview, ONTAP - How quotas work with users and groups
