FAS2240:  An Inside Look

The FAS2240, NetApp's new entry-level system, is designed to help you start right, keep it simple and grow smart. A full HA configuration fits in the space of a single disk shelf and converts to a disk shelf when it’s time to upgrade. High-speed network options, triple the performance and rugged design make the FAS2240 perfect for space-limited and extreme environments. A recent Tech OnTap article by Steven Miller discusses the details of the new platform including innovative packaging, important speeds and feeds and RASM capabilities.

What do you think about this new entry-level storage system? Does it meet your needs?

    Hi!!

     

    I think this is a really inovative release! Connectivity (SAS, FC and Ethernet bandwidth was increased) is now at the same level of the other players like EMC or IBM. SSD drives is also another advantage.

     

    But I think FAS2240-4 doesn't support SAS disks at the base chassis is a big problem! Will it support this configuration? Do you have a date for this release?

     

    Thanks in advance!

      Hi Rafael,

       

      We don't plan to support SAS in the FAS2240-4 model.  The disk industry is shifting from large form factor (LFF) SAS disks, like those used in the DS4243, to small form factor (SFF) 10K SAS disks like those used in the DS2246.  As a result we anticipate no further capacity increases in LFF SAS disks.  As such we don't intend to support a disk type undergoing a  transition in the new FAS2240.

       

      Take care,

        Hi Chris!

         

        Thanks a lot for the fast and useful reply. Since there is a trend directing drives to SFF standard, do you know if SFF disks spinning at 15k RPM will be released soon?

         

        I am concerned about this because we won a deal with VDI some months ago and we positioned FAS2040 for do this job. We are planning to replicate this project to more sites using FAS2240, but we really need 15k RPM drives. To do it with FAS2240 we would need to waste all the controller's drives, and add one or more shelves to meet the need.

         

        Thanks again!

          Hi Rafael,

           

          Although you have 10k internal disks in the FAS2240-2 compared to 15k internal disks in the FAS2040, in theory the FAS2240-2 will provide more IO than the FAS2040 in 2RU of space.

           

          Using NetApp's IOPS throughput in their subsystem document you will get 140iops per 10k data disks, while each 15k data disk will give you a whopping 172iops.

           

          With a single controller environment; in a FAS2040 with 12 internal drives you will only have 9 15k data disks giving 1548iops. While the FAS2240-2 and its 24 Internal drives will give you 21 10k data disks or 2940iops.

           

          In a dual controller environment the difference between those numbers are even greater (in favour of the FAS2240A-2).

           

          Therefore in every case a single FAS2240-2 will provide you much better performance than a FAS2040A, when fully populated.

           

          But I hear you, 2.5" 15k SAS drives would be nice!

        One of our solutions that we are considering implementing would require some storage arrays to have Solid State Disk (SSD).  The write IO's are high, but the storage space requirement is not.  We can throw extra spindles in to get the write IOPS, but waste 90% + of the space, and have additional power and cooling to deal with. 

         

        Data ONTAP 8.1.1's hybrid aggregates seems ideal as it will allow us to size the aggregate correctly and still get the performance we need.

         

        Now for the question, will the FAS2040-4 model support SSD in the base enclosure?     The SSD is SATA based, as is this enclosure, and both are 3.5", and the SSD is supported in the DS4243 shelf, which is what the FAS2040-4 is.  Can you confirm the SSD compatibility?

    Hi, does anybody know if Converged Network Adapter is supported in FAS2240? It would be just great to use FAS2240 with CNA to get both FC connetivity and cluster-mode... Imagine those possibilities... :-)
