  2. How much bandwidth is enough?

    How much bandwidth is enough?

    How much bandwidth is enough? The instinctual answer, born from harsh experience always seems to be “more than is available”, but is this actually true? As with anything in IT, the answer is “it depends”. Fortunately, most of the key variables can be quantified.

  4. Testing the Limits of the Dell H710 RAID Controller with SSD

    Testing the Limits of the Dell H710 RAID Controller with SSD

    Several of xByte’s customers have asked if the Dell H710P controller would ultimately limit the performance of a large number of SSD’s in a server.  While it seems that it would be a bottle neck, I didn’t have any test data that would show to what extent the H710P would limit SSD array performance.  I therefore could not definitely advise our customer on the best number of SSD drives to serve their needs.

  5. Using CacheCade to get 15K performance from 7.2K Drives

    Using CacheCade to get 15K performance from 7.2K Drives

    Often there is performance tradeoff between large slower drives and smaller faster drives.  SAS 15K drives provide phenomenal performance but their limited size can result in lack of usable disk space.  Conversely, Near Line SAS drives offer huge amounts of usable space but their performance is lackluster.  This performance gap can be filled using the CacheCade feature on some Dell PERC controllers that allow the use of SSD drives as read cache.

  6. Dangers of RAID 5 Array with SATA Drives

    Dangers of RAID 5 Array with SATA Drives

    For many in the tech industry, RAID 5 has always been the recommended RAID level when creating new arrays.  When I was first deploying a new iSCSI SAN for xByte, I found strong recommendations against using RAID 5.  I took the advice and deployed a 17 disk RAID 6 array.  With 17 10K SAS drives, performance was more than we needed.  Now with added role of Sales Engineer, I wanted to revisit the dangers of RAID 5 more completely so we can give the best advice possible to xByte’s customers.

  8. Best uses for servers that have been replaced with a hyper-converged environment

    Best uses for servers that have been replaced with a hyper-converged environment

    Don't let your previously used servers go to waste! Having a good reuse plan can make justifying the cost of new servers and/or a hyper-converged infrastructure easier.

  9. Does 15K SAS still make cents?

    Does 15K SAS still make cents?

    I am sure there are occasions where drive performance doesn’t really matter and you can’t justify spending even a little more to get faster performance.  But why limit yourself?  Prices for solid state drives (SSDs) have come down so much over the past couple years making it difficult to justify buying spinning disks, especially the more expensive 15K SAS drives.

  10. Deployment Scenarios for the Dell PowerEdge FX

    Deployment Scenarios for the Dell PowerEdge FX

    The Dell PowerEdge FX enclosure might, at first, be a bit of a mystery. For all intents and purposes, this is a 2U rack mount blade chassis and, in many ways, it is the baby sibling of the 5U VRTX enclosure.
