Direct Attached Storage (DAS)
DIRECT-ATTACHED STORAGE (DAS) ENCLOSURES
Direct-Attached Storage (DAS) hard drive enclosures add capacity directly to an existing server or cluster of servers without the need for a network interface. This is usually the simplest and most cost-effective way to increase storage space. Dell PowerVault storage arrays have evolved over the years from the older PowerVault 220S SCSI enclosure to the roomier PowerVault MD1000 SAS/SATA array which allows for up to 30TB of storage space.
For two-node clusters or direct connection for up to four servers, the PowerVault MD3000 allows pay-as-you-go expansion options to daisy-chain up to two additional PowerVault MD1000s. More recently, Dell’s Powervault MD1200 and PowerVault MD1220 models saw an increase in throughput with 6GB/s hard drives and controllers. The PowerVault MD1220 will accommodate up to twenty-four (24) 2.5" hard drives for a maximum capacity of 28.8 TB. The PowerVault MD3200 allows even more expansion and connects to additional MD1200s or MD1220s.
