Check setting up threshold in SPA online help guide.

where it will send the alert if we configure ..? will it send to any email address or where we can set the email address to which the alert will come ..?

Wasn’t 70% the absolute maximum at which forced flushing would start?

I assume this is for WP counts.  I would set that alert at 60%. 

I don't see the COnfiguer Alert & Emain Notification under ==>Tasks ==>Monitoring ==>Alert Configuration.

I can see only below three :

Config Pool Utilization thresholds

Enable/Disable Alerts

Configure DSE Spill Threshold....

Yes, you need to configure email alerts from SMC first:

1) Open SMC console. Go to task. Click on configure alerts and email notifications.

2) Click on Change email notification button.

3) Click on config email server

4) Enter the following information:

Sender email: @emc.com

Email Address From            : sender_email id@emc.com

Receiver/To Email address :

SMTP Server                       : and port 25

5) Make sure your SMC host is added on the mail server for open relay otherwise mails sent from this host will be blocked by your mail server.

6) check if test email works fine. If yes then configure email notification in SPA's threshold and alert window. Below snapshot is from the SPA online help document.

we have SMC v7.2.1.3.

I do not see any attachment. What is your SMC version?

Here is the screen attached:

The Symm has low priority destage at 50% of writable cache (40%) total.  If you are above this, you are in high priority destage.  Once you hit the system max WP limit, you are in real trouble.  You don't really want to be there, which is why you want the threshold above the high priority water mark and below the system max WP limit.
