<div dir="auto">Many network storage engineers simply don't understand bandwidth (or the importance of port groups)... With an ESS you are talking GIGA*BYTES* per second and storage and networking architects simply see 10Gbe and assume that's good enough. A 10Gbe connection can do about 1.4GB/s.. 100Gbe can do 12.5GB/s. To the wrong engineer you can explain this until you're blue in the face and they won't get it. You need to divide Gbe by 8 to get about the GB/s throughput. Explain to them that a USB-C interface is capable of 10Gbe... So you're throttling millions of dollars in technology to the speed of a consumer grade USB-C interface. When infact an ESS can drive at least 2x100Gbe to saturation.<div dir="auto"><br></div><div dir="auto">I don't have an ESS but a classic SAN array and Spectrum Scale and I can saturate 32*8Gbe fiber connections.</div><div dir="auto"><br></div><div dir="auto">Alec</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Jun 5, 2023, 8:56 AM Andrew Beattie <<a href="mailto:abeattie@au1.ibm.com">abeattie@au1.ibm.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<div dir="ltr">This will allow you to adapt from the QSFP+ 100GB transceiver down to a SFP+ 10GB transceiver and then use standard OM4 cable and Cisco 10GB transceivers at the other end.</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">However I will also comment that using 10GB network for an all flash ESS is a bit like buying an F1 racing car and never taking it out of first gear. </div>

<div dir="ltr">You would honestly be better investing in a single 100GB switch to at least build the ESS cluster at 100Gbit and getting the full potential bandwidth from your investment in NVMe </div>
<div dir="ltr"><br>
</div>
<div dir="ltr">Otherwise buy a FS5200 + 2 x86 servers and some scale licensing, because you are down rating the ESS3200 to less than 25% of its potential performance </div>
