They provide excellent integrator support but the complete systems MUST be tested and burned-in after assembly. We build them up with the best components BUT we do a 168 hour burn-in and then test again afterwards. Once a unit has been burned-in for 168 hour with no failures, we have seen less than a 0.1% system failure rate over the first 3 years. BTW, we see a >5% failure rate of disk drives during burn-in. Infant mortality is horrendous on disks. Especially on Seagate drives. We have a program we wrote in house just for disk / RAID array burn-in and performance testing under CentOS. I agree with John: Any system is only as good as the integrator that builds, test AND burns in its products.
