Right now, I have 5 racks of USR Total Control with Netservers and quad modems. My leases are expiring over the next 6 months, so I need to decide if I renew the leases or move to HiperDSPs. How are the HiperDSPs working vs the quad modems? Are the HiperDSPs every bit as good as the quad modems? Will every modem that works now continue to work? I'm not sure the Netserver cards aren't limiting the throughput of my modems. Would getting HiperARCs to go with the quad modems be the best of both worlds?
