Just to highlight a few things in this list, assuming it checks out: 1. 40GB of memory is quite good! The z114 was available with as little as 8GB usable main memory, but you’ve got 5 times that amount (4 memory increments up from the minimum). That’s a win. Maximum for the M05 physical model was 120GB. This memory is RAIM protected (Redundant Array of Independent Memory), and the 40GB figure refers to usable memory, after accounting for HSA and RAIM overhead. 2. STP (Server Time Protocol) is another win. That’ll mean you can synchronize your z114’s system clocks with an external time source via (S)NTP. For example time.nist.gov should work. 3. CPACF is another win. As Parwez mentioned, CPACF was an orderable option (Feature Code 3863), albeit no additional charge. Yours is enabled, which is great. It also means your machine is subject to possible export and import regulations in the unlikely event if you ever decide to sell this machine to some buyer in another country. CPACF on the z114 is sufficiently advanced enough to accelerate up to AES-256 encryption/decryption and up to SHA-512 (SHA2) hashing. The hashing acceleration is actually on every machine, but the AES-128/192/256 part requires Feature Code 3863. This’ll be clear key encryption without Crypto Express adapters, but the important part for your home lab is that you pick up the acceleration, typically for TLS. 4. OSA-Express3-2P 1000BASE-T means you’ve got copper Ethernet ports. They’ll be perfectly fine, and they support everything you could want (all network types) including OSA-ICC (the Integrated Console Controller) if you need that. I believe in that generation (OSA-Express3) they’ll auto-negotiate 10/100/1000 speeds and full/half duplex (if you wish), so it’s obviously best to configure 1000 and full duplex in your switch and on the machine. Standard Cat 5 cabling is all you need. If I/O cards have been removed that’s not necessarily a bad thing since that might reduce power draw at the margins. 5. The A01 capacity configuration is 1000% better than the possible ICF-only configuration that would’ve been really bad news. — — — — — Timothy Sipples Senior Architect Digital Assets, Industry Solutions, and Cybersecurity IBM zSystems/LinuxONE, Asia-Pacific sipp...@sg.ibm.com ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
