Which IBM DS-Series Product is Which NetApp E-Series Product?

image5NetApp’s E Series line of servers is the same as those from IBM’s DS line. Just as with the N Series, IBM simply rebrands the NetApp servers with their own logo. Unlike the N Series, IBM is actually continuing to use the E Series as their DS line.

However, those companies that have both N and DS products and who need to upgrade to one of the NetApp FAS servers may want to consider moving over to the E Series through NetApp. Having all of the storage devices from one company can make data far easier to manage.

NetApp offers several high quality servers in their E Series line. These include E2600, E2700, E5400, and E5500. All of the machines come with dual controllers in 4U/60, 2U/24, or 2U/12 shelf.

The E2600 machine features a maximum raw capacity of 768 TB. It has 192 maximum disk drives and 4,000 MBPS maximum sustained bandwidth. The cache memory is 4 GB and it offers a number of IO interface options – SAS, FC, and 1 GB and 10 GB iSCSI. The E2700 machine also has a maximum raw capacity of 768 TB and 192 disk drives. It offers a max sustained bandwidth of 8,000 MBPS. The cache memory is 4/8 GB standalone simplex or 8/16 GB HA Duplex. Interface options include SAS, FC, and iSCSI ports. These correlate to the IBM DS models DS8700 models 941 and 94E. Various expansions are available to expand the properties.

The E5400 has a 1,536 TB maximum capacity and 384 maximum disk drives. It has 6,000 MBPS sustained max bandwidth, and offers 12 GB or 24 GB cache memory. It has eight 8 GB FC base powers, as well as eight 6 GB SAS ports, eight 8 GB FC ports, four 10 GB iSCSI ports, and four 40 GB IB ports. The E550 also has a 1,536 TB maximum capacity drive and 384 maximum disk drives. It has a maximum sustained bandwidth of 12,000 MBPS and 24 GB cache memory. The server has eight 6 GB SAS ports, eight 10 GB iSCSI ports, eight 16 GB FC ports and four 40 GB Infiniband ports. These correspond with the DS8800 951 and 95E. As with the other machines, it’s possible to add expansions to change the capacities and configurations.

 

Because of the sheer number of expansion modules and options with all of the different DS and E series machines, it’s important to understand just what features your server has. Since you will be able to work with the exact same type of machine if you transfer from IBM back to an E Series machine, it should be easy to ensure parity between all of your devices.
