Tuning Letter 2019 No. 2 Published
Good news for all our Tuning Letter subscribers - the 121-page 2019 No. 2 issue of the Tuning Letter is now available on our Publications website. This issue includes: An article about the CA/Broadcom products that exploit zIIP processors. Nearly every Z installation has zIIPs, but trying to identify the products that should be exploiting those zIIPs can be quite a 'challenge' (we know, we tried to do that and have the gray hairs to show for it!). So we worked with Mike Patriarco in...

z13 and z13s End of Marketing Date Approaching
This is just a short post to remind everyone that the End-of-Marketing date for z13 or z13s upgrades is just a month away. Upgrades that involve real hardware (such as additional channels or zEDC cards or coupling adapters) must be ordered by June 30, 2019. LIC-only upgrades can be ordered up until June 30, 2020 (refer to IBM US announcement letter 918-110 for the details). This is especially important for anyone that has one or more z13s CPCs with InfiniBand Coupling Links. The IBM ZR1...

SHARE in Phoenix
Hi from sunny Phoenix! Cheryl, Brenda, Mario, and myself arrived here yesterday evening and are looking forward to an exciting week. After my first pass over the list of sessions, I have 117 presentations that I would like to see. And that doesn't include the closed door sessions, one-on-one meetings, and lunches and dinners that we've arranged with some of our customers - I can tell already that I'm going to have to go on another diet when I get home. For a change, we are...

Tuning Letter 2018 No. 3 Available
Hi All, The latest issue of Cheryl Watson's Tuning Letter is now available on our publications website. This one took a little longer to deliver than originally planned.

The Table of Contents will be available on our public website tomorrow for anyone to view. This issue...
Something for Everyone in October
It's been a while since our last blog post, so we thought that we would pass along some recent news to brighten your mid-week for you. First, in case, you missed it, IBM announced their mid-life update for the z14 and ZR1 CPCs. IBM US Announcement Letter 118-075, issued on October 2nd, lists a number of new and enhanced functions. First up is a new CFCC Level (23) with a new function that should be especially popular with anyone that has a sysplex that spans many kilometers. Also of...
