Page 6: Limitations Of This Release
Note Dell strongly recommends that clusters with DX Storage volumes originally formatted with releases earlier than version 2.0 (September 2007) be upgraded to the 5.0 release as soon as possible so the volume recovery process from recent software versions remains compatible with the older disk format. - Page 7 Many enterprise or server grade disks are designed to return errors within a limited period of time, allowing recovery or rebuild operations to begin immediately and to eliminate the lengthy delays on I/O operations. Dell recommends against the use of consumer grade disk drives and does not support them in a high demand environment.
- Page 8 present in the cluster. If your client has a priori knowledge that a certain object is stored, it should retry the request until it succeeds. Normally, only a single retry will be required. • Network Interface Required. Every DX Storage node requires a working network connection. If a network cable is unplugged or if the network is not operational at any time during or after startup, neither SNMP nor SCSP are available.
