Distributed cache size limit

Question

Hi,
I want to create a distributed cache with 2 node.
Each node can have maximum 500 entries.
Total entries in cache of both node together should not exceed more than 1000.
If user try to put more than 1000 element in cache then some old entries from cache (LRU, LFU) should be removed from cache and new entries should be added.
Can you please help me with the schema for the above scenario.
Your help will be appreciated.
Thanks & Regards,

Hi,
I tried below code <high-units> was not working
Cache size is 1010  (greater than 500)
Java code
package com.splwg.ccb.domain.pricing;
import com.tangosol.net.CacheFactory;
import com.tangosol.net.NamedCache;
public class CoherenceSizeTest {
     public static final int NO_OF_MAIN = 4;
     public static void main(String[] args) {
     NamedCache cache = CacheFactory.getCache("CheckSize");
      for (int i = 0; i < 1010; i++) {
            String key = "key" + i;
            cache.put(key, new Long(i));
     System.out.println(" Cache size : " + cache.size());
config file
<?xml version="1.0"?>
<!DOCTYPE cache-config SYSTEM "cache-config.dtd">

    <caching-scheme-mapping>
        <cache-mapping>
            <cache-name>CheckSize</cache-name>

            <high-units>500</high-units>
            <autostart>true</autostart>
        </distributed-scheme>
    </caching-schemes>
</cache-config>
