Five years. That's the longest runway you can put under an SR550 without rethinking your whole stack. This Lenovo Essential Service plan covers 24×7, hits a 4-hour response target every single time, and includes YDYD parts delivery — all for five full years. If a RAID controller throws a tantrum at 3am on a public holiday, you call, an engineer answers, and the fix is in motion before your first coffee's gone cold. Lenovo ISG backs the whole thing. Add to cart when you spec the server out or layer it on top of an existing build
