Specific KBs are required, see MS hardware spec siteĭisk calculations are based on using 72 GB 10,000 RPM drives as detailed in the Microsoft Spec.Ģ x 72 GB drives in RAID 1 gives: 72 GB capacity and 232 mixed total IOPS.Ħ x 72 GB drives in RAID 1 gives: 216 GB capacity and 697 IOPS. Lync 2013 doc suggests 66/33 read/write IO profile (700/350 iops per LUN)ĭoesn't say how teaming to be done, so NFT only seems appropriate Shared resource techniques, including processor over subscription, memory over commitment, and I/O virtualisation, cannot be used because of their negative impact on Lync scale and call quality.MS Assumptions in 2013 virtualisation guide The disk IO and capacity requirements are also listed here. Most of the notes are bullet points taken from the Lync 2013 virtualisation guide, but I have put a section at the bottom to try and translate the official 2015 hardware requirements. Microsoft won't support a configuration with hardware less than recommended which makes the hardware requirements for an organisation with under 10,000 seats seem even higher. The smallest enterprise set up that Microsoft details is for 10,000 seats. There aren't many corners that can be cut when setting this up and the hardware requirements are pretty large. I've been looking through the MS hardware and virtualisation guides for Skype for Business 2015 (and Lync 2013) and put together some notes to try to translate some of the best practices.
