The Dell PowerEdge 1950 has several controller options available. However, unless you're working with more than two hard drives in a 2.5" chassis variation, your RAID options will be limited to RAID 0 and 1. Earlier generations featured an internal PERC 5/i controller offering RAID 0, 1, 5, 10 & 50. The PERC 6/i controller introduced integrated memory cache and RAID 6 & 60 options.
A rechargeable lithium-ion battery back-up (BBU) was provided with most models to protect write cache in the event of a sudden power failure. These batteries are known to eventually lose their ability to hold a charge. When this happens, the battery must be replaced. There are also external and non-RAID controllers available.
Unless otherwise noted, controllers are refurbished, tested and pulled from working servers and backed by our 90-day parts replacement warranty.
