HPE Alletra 6000 Peer Persistence iSCSI subnets

[CadenLange]

Hi all

I'd like to confirm that's it's still supported for Alletra 6000 arrays to operate with a single iSCSI subnets (rather than using two separate iSCSI subnets) and then to use IP address zones to prevent unnecessary VPC traffic between the switches.

Also, specifically if this configuration is qualified for Alletra 6000 Peer Persistence environments.

many thanks in advance

Hi CadenLange

As part of the initial setup, two or three IP address subnets should be created on the first array. For iSCSI arrays, ideally, separate subnets are dedicated to management, group, and data traffic.
If desired, the group traffic can be run on the same subnet as the management or the iSCSI data traffic, but it is important to maintain a latency of 5 ms or less for the group traffic

After the subnets are defined, it is necessary to bind them to specific ports on the array controller. Remember that high availability is very important for Peer Persistence, and make sure that each subnet is assigned to at least two ports per controller. This arrangement enables routing through redundant switches for a more robust configuration.

for more information please go through the "HPE NIMBLE STORAGE AND HPE ALLETRA 6000 PEER PERSISTENCE Deployment considerations for NimbleOS 5.1 and later" Document.

Hope this helps.!!

Hi,

Yes it is supported, according toData Protection team. The only network requirement that we have is a 10G link between sites w/ a round trip latency between site of 5ms or less.

Hope this answered your query.
