      Comments and questions regarding the globalSAN iSCSI Initiator and Xtarget Storage Server

    • Why is globalSAN so slow compared to ATTO Xtend SAN?
      We received a support case for this ticket as well, and it was apparent from the screenshots that Error Detection (CRC32C) was enabled in globalSAN, and not in the other initiator. The initiator itself should not be affecting the speed, but the CRC policy does tell the operating system to perform extra calculations for every transfer, and the impact is especially noticeable when using 10Gb. Turning it off in globalSAN or enabling it in the other initiator should result in consistency between the two. The slower read speed is most likely a connectivity or configuration issue. There may be an MTU mismatch in ports on the workstation, switch, or storage. OS X also often requires some stack tuning to optimize 10Gb performance, and many adapters have recommendations for this. We'll watch for an update to the support case.
    • Why is globalSAN so slow compared to ATTO Xtend SAN?
      I am using the trial version of the initiator to connect from my iMac 5K to my DS2015xs via SFP+. The unit is loaded with 8x8TB drives. When formatted to be a "normal" SAN with SHR-2, I get throughput both ways between 350-500MB/s. When I format it RAID-6 in block level iSCSI, I get 350MB/s write speed and 150MB/s read speed with the ATTO, and about 150MB/s write and 80MB/s read with the SNS. Clearly I have a problem with the read speed in both cases, however the SNS being half as fast as the ATTO is alarming. Any suggestions? I'm using the default settings, and even twiddling them on both ends didn't yield any improvements.
    • EVO Shared Storage Boot Drive
      Additionally, please note that depending on your EVO model, there may already be a spare drive included in the rear of the chassis. On current systems, the EVO configuration data is replicated across the data disks to provide for an automatic recovery in the event of OS disk replacement. Let us know and we'll be happy to help with the transition, if needed.

      Hi, Please contact us using the Contact Support link and we'll be able to look into your support options.  Please make sure to include the SNS number on the back of the EVO if applicable. Regards,
