In ISE (ise-3315) low reliability

[Vlad Voronko]

Hello.

What will happen if ise- 3315 broke one HDD? In ISE low reliability - RAID no. How can a server for security do without RAID?

How can we improve reliability?

[Tarik Admani]

You can purchase another appliance and run them in a distributed deployment, where one is failover, and the other is standby. Or you can upgrade to the 3355 which has the raid controller.

Thanks,

So sorry. Unfortunately, we already bought ise-3315. We'll do the cluster. I think nowadays the possibility RAID1 on the server must be a priori. Thanks Tarik.

You just bought the low end appliance One thing to also consider is that you can have additional nodes running in VM Ware...if you don't want to purchase additional hardware

Thank you for rating!

Hello,

For the reliability in ISE, you need to buy one more ISE same appliance.

[Ravi Singh]

You have to purchase a new 3315 device and deploy ISE in distributed  environment and configure HA. For configuring HA you can see Configuring Administration Cisco ISE Nodes for High Availability

Hello,

Even  if the RAID option is present, two appliances should be bought to configure them  in HA, so that operations are not disturbed in case any issue occurs  and one of the box goes down due to any issue other than HDD.

Hello Vlad,

I think that you might have got your answer from the above SME's , yes they are absolutely correct that you need to go for High Availabiity for more realibility that can be either with the two hardware appliances or with the two ISE in the virtual environment.

The best solution is going for the higher appliance or VMware solution for reference kindly see the following details
