  • Hi,

    if your CAS is down, you can still work with your primary site. You will get into replication trouble and even loose data after an offline time longer than 14 days. If you know that your offline time will be shorter than those 14 days, you will not get into trouble. This 14 day duration needs to be configured, I think the default value was 5 days.

    if you have a secondary sites and loose the connection to the primary, you are not able to manage the secondary sites since the SCCM console is only connectable to primary sites and CAS. The MP on your secondary will still collect client data which will be transmitted to the primary after an reconnect.

  • That's not to say everything will "work" though. There are certain things a CAS is responsible for if you have one in your environment so if its down, ultimately, no your environment will not continue to function as normal so I would never consider this as acceptable and you need to restore functionality to the CAS ASAP.
