    Actually, PCIe SSD have considerably better performance that the SATA or SAS SSDs. The use of the PCIe provides much higher bandwidth and lower latencies -> fast throughput, more IOs.

    Support for PCIe SSD devices

    The availability of PCIe SSD adapters has exploded in the last 12 months. I don't, though, see any of these devices list on the HCL.

    Are there any plans in this area, or is it a case that as...

    I don't know if defragmenting would actually accomplish anything.

    Since iSCSI LUNs are virtual block IO devices, the seek time optimization which a defragmenter provides would be of little value,...

    Roel,

    Although Open-E support for TRIM is important, the larger problem is that Adaptec/LSIU and Areca do not support TRIM in their RAID disk controllers.

    There are some SSDs which support...

    @Al-S,

    As far as I can see the graph/stats are the same as V6, and are equally as criptic. So, the answer for dagar is: No, there are no changes in the graphs/statistics.

    Todd,

    To be clear, I am not looking for the DR to be part of the cluster. I am looking for the DR to simply be a backup of some cluster volumes.
  8. Active/Active with separate storage or with shared storage?

    Am wondering about the new Active/Active functionality as it relates to how the systems would be configured.

    Some other active/active solutions have two servers/heads/controllers which are...
  9. Active/Active and replication for DR backup?

    I haven't had a chance to download the new version, so forgive the question.

    Does the Active/Active failover pairing also support having a replication task to an additional/third (DR) location?

    I think you will also find that Windows Server 2012 has had improvements in failover tolerance.
  11. Active/Active Licensing -- per node or per Active/Active node pair?

    The price list is not clear on this.

    In future, I would suggest that a more "direct" answer would be appropriate.

    By "direct answer" I mean:

    Define/clarify what you mean by "work in the cluster".

    Do you mean, the VM can run as part of a VMWare HA cluster? Yes.

    Do you mean, the open-e Lite can host storage in open-e active/passive...

    It is not surprising for a vendor to try to dismiss another vendor's products.

    One thing to consider... does the AvroRAID product support the same feature set as Open-e? Volume Snapshots?

    In order to be used as a read cache data must be written to the SSD.

    The card/software decides what blocks are used most often and writes those to disk first, then to the cache. (So, if the SSD...

    I would wonder if "dd" does a random IO test and "iozone" does a sequential IO test.

    There is a significant difference in the performance of the 2 methodologies.
