Lenovo ThinkSystem DS4200
The Lenovo Storage DS4200 was an entry-to-midrange hybrid SAN storage array built on Dot Hill / Seagate AssuredSAN OEM architecture. Offering dual active-active RAID controllers with Rapid tiering, thin provisioning, and asynchronous replication, it provided dependable block storage for small and medium-sized enterprise virtual environments. Available in 2U12 LFF and 2U24 SFF enclosures, it supports 16Gb Fibre Channel, 10Gb iSCSI, or 12Gb SAS host connectivity. It was later replaced by the ThinkSystem DE Series (DE4000H). On the secondary market, buyers should test controller supercapacitor and flash memory backup health, check that drive caddies include genuine DS series interposers, and confirm firmware compatibility across both controllers.
