One 10/25/100 GbE switch is required. Multiple switches may be used for high availability and load balancing purposes. Separate (one or more) 1 GbE switches may be used for the VxFlex OS management network. Dell EMC VxFlex Ready Node AMS User Guide...
Page 23: Ip Addresses
If the node does not have a 1 GbE port, minimally a BMC (iDRAC) port is needed. IP addresses Refer to "IP Addresses" under Networking in the Architecture section, which explains the required network configurations for VxFlex Ready Node. vCenter support vCenter 6.0, 6.5 and 6.7U1 are supported.

Page 28: Mdm Cluster Modes
All members of the MDM cluster have the same MDM package installed on them. Before a server makes its way into the MDM cluster, it must follow the following path: 1. Install the MDM package on the server. Dell EMC VxFlex Ready Node AMS User Guide...

Page 30: Protection Domains And Storage Pools
Each Storage Pool can work in one of the following modes: Zero-padding enabled Ensures that every read from an area previously not written to returns zeros. Some applications might depend on this behavior. Furthermore, zero padding Dell EMC VxFlex Ready Node AMS User Guide...
Page 31: Acceleration Pools
By grouping them into a Fault Set, you are configuring VxFlex OS to mirror the data for all devices in this Fault Set. The mirroring should take place on SDSs that are outside of this Fault Set. Dell EMC VxFlex Ready Node AMS User Guide...
Page 32: Data Layout
For FG, you must have NVDIMM configured as a DAX device. After NVDIMM is all set up in your environment, you need to configure an NVDIMM Acceleration Pool (for more information on Acceleration Pool, see "Acceleration Pools") and then you can Dell EMC VxFlex Ready Node AMS User Guide...

VxFlex OS maintains the user data in a RAID-1 mesh mirrored layout. Each piece of data is stored on two different servers. The copies are randomly distributed over the storage devices. Rebuild and rebalance processes are fully automated, but are configurable. Dell EMC VxFlex Ready Node AMS User Guide...
Page 34: Rebuild
The rebuild I/Os are limited both in bandwidth and in the amount of concurrent I/Os. As long as the number of concurrent rebuild I/Os, and the bandwidth they consume, do not exceed the predefined limits, rebuild I/Os will be served. Once Dell EMC VxFlex Ready Node AMS User Guide...
Page 35: Rebalance
Rebalance, unlike rebuild, does not impact the system’s reliability and therefore reducing its impact is not risky. Note: Rebalance throttling affects the system's performance and should only be used by advanced users. The following possible priority policies may be applied: Dell EMC VxFlex Ready Node AMS User Guide...

Each hardware vendor defines specific thresholds for the S.M.A.R.T. attributes. This feature currently supports storage devices controlled by LSI, HP and Dell RAID controllers, and stand-alone devices. During system deployment, an external monitoring tool is installed as part of the LIA on each node. Additional RAID controller tools must be installed manually after system deployment: storcli for LSI RAID controllers, hpssacli for HP RAID controllers, or perccli for DELL RAID controllers.
