Last week I did an OE upgrade on an EMC VNX2 Series SAN.
All pre-checks passed, new files downloaded, ready to go right? No.
Go to proceed to start the upgrade with my domain admin user via LDAP, and can’t proceed due to “Insufficient CLI Permissions”. Weird. Never mind, I’ll log back in with the root/sysadmin user.
Hold on, that doesn’t have permission either? Knowing full well I can log in manually if needed, so why won’t the upgrade work?
Turns out that if you have complex passwords with special characters, the upgrade bombs out with an error.
Quick work around is make a local admin user for the upgrade with a simple password and use that and delete it when done. Not ideal but it works I guess.
I know it’s not only EMC products that let you set a password with special characters and complexity, then break login due to “invalid” characters. Why do vendors allow this to happen in their software?
Better than another vendor that allows long passwords but only stores the first 8 characters…
So we got some new Dell M630 Kit to Virtualise SQL.
One of the briefs was to match the performance of the existing physical hardware. While this was not too challenging CPU/RAM wise as the existing kit was 5 years old.
What was interesting was the existing PCI-E Fusion I/O cards in the Dell M610X’s we had. Dell no longer offer a “full height” blade to facilitate the PCI-E cards anymore. Instead they offered us their new NVMe PCIe SSD Cards, at 1.6TB each, theyre certainly not lacking in space.
What is not lacking either is performance. Holy hell these things are fast! While i have only had them for 2 days and limited testing, based on SQL-IO testing done between the two systems, the NVMe drives are approximately twice as fast for 8K Rand RE/RW, and 3 times faster for 64 Seq RE/RW!
Thanks for coming to this new venture of mine, ive decided to start a bit of a blog, no idea how long it will last.
Ill be blogging about my works with Cisco Network/Security/Wireless, EMC SAN/NAS, and VMWare technologies
My blogs are my own, they do not represent my employers past, present or future.
