I have an obnoxiously connected home, all built around a Gen1 SmartThings Hub. I mix ZigBee, Z-Wave, Wifi and home-grown RPi or Arduino controlled devices. Hopefully this post will show some of the available options out there, and some of my recommended products
Recently, High Availability was accepted as a Nvidia East Coast partner to sell and manage their Nvidia DGX-1 GPU platform, as well as reseller of PureStorage’s new ARIA (AI Ready Infrastructure) and the Cisco UCS 480 ML M5 GPU Server.
When you think about PureStorage Orange, Winter time, and High Availability, what comes to mind? Pumpkin Spice Lattes? Why not ‘Pumpkin Spice Machine Learning’?
Often before conferences, I tend to make a post for first timers. I never created one for BSidesLV or DEFCON before.
These are just my experiences and recommendations.
Do your own thing! Make the conference about what YOU want it to be about!
(That was tip #1)
I’ll be adding to this often as my brain remembers stuff.
FYI, ran into an issue tonight working with VVOLs.
I had just upgraded my PureStorage array to Purity 5 GA release and wanted to jump into VVOLs on my lab.
Customers will not be able to use vvols unless they manually install FNIC driver 126.96.36.199 or higher.
VVOLs are not supported on any VICs with the drivers installed from the current Cisco-branded v6.5 and 6.5U1 ESXi ISOs.
This is Cisco bug CSCux64473 Specific cause is because included driver did not support “Secondary LUN IDs”.
If a customer tries, their Protocol Endpoint will just never show up.
Symptom: UCS server with VIC adapter does not support VMware Virtual Volume feature
Conditions: When attempting to access Virtual Volume from UCS servers installed with VIC card.
Workaround: Virtual volume is not supported on any the VIC cards / FNIC drv ( Their but report isn’t totally true, I tested 188.8.131.52 driver and it worked great!)
- Latest driver release does work:
Now, after updating the driver and rebooting my servers, VVOLs is working awesome!
PureStorage does VVOLS right!
Fast does not always mean high IOPs. Sometimes hundreds of thousands of IOPs just is not enough. Big data applications such as machine learning, real time data processing, and backups of big data workloads needs high throughput and massive scaleout. Enter PureStorage’s FlashBlade!
Got DataDomain? Got DD OS 6.0? Your #VALID data may be getting deleted and you don’t even know it!
UPGRADE TO DD OS 184.108.40.206 IMMEDIATELY!! (Or DD Virtual 3 Update 1)
Segments ingested while the unit is in a cleanup cycle may be deleted, as the unit incorrectly marks them as invalid. You would not know you lost these segments until you attempted to restore!
Intel recently screwed us all with the Atom C2000 processors taking a massive crash and burn on end users, leading to all sorts of embedded devices turning into giant paperweights. This week, Intel blessed us with an exploit in the wild hitting their Advanced Management Technology (AMT).
AMT is their ability to remotely configure and control desktop and server systems via web service calls. Firewall off where ever possible ports 16992 and 16993, though if someone get’s inside, it’s a free for all. A Pseudo-Patch has been created. Apply it today!
GitLab certainly had a #SucksToBeYou week. Earlier this week, an admin at GitLab had the same thing happen. Too tired, rm -rf in the wrong location, but unfortunately they had poor backup practices.
Props to them for being upfront.
IF they had Netapp gear, or Cloud Ontap, they could have used SnapRestore or Single-File SnapRestore to pull back the deleted files from snapshots within seconds.
Just a heads up – Isilon OneFS: Nodes containing Mellanox ConnectX-3 adapters may unexpectedly reboot after running for 248.5 consecutive days, which may result in data unavailability ( ETA 491747 )
This primarily hits systems with OneFS 7.2.1.
Reboot those nodes ahead of time or patch if possible! Otherwise, it’ll #SucksToBeYou!
Cisco announced that a clock module in certain products may have a failure after 18months. This one is big, and this one is bad!
