Re: [ADSM-L] RTC on DB SSD disks

Hello Robert,

The key with the real-time compression on v7000 is to buy the compression add-in card that IBM supplies. That offloads all compression workloads from the primary CPU/RAM on the v7000 controllers and makes a big difference in IO throughput.

That said, TSM databases tend to be pretty IO intensive. In our organization, the TSM database luns are the busiest in the company by a fair margin. Unless you're really strapped for cash, I'd say you're better off to buy the capacity and not compress the TSM DB. Even some IO degradation could make a big impact to your daily operations.

Hope that helps,
