Deploying Storage Spaces Direct – Part 36 – Virtual Adapter Affinity S2D Deployment #PowerShell #MVPHour #StorageSpacesDirect

Hey Storage Spaces Direct fans, I have been on Vacation for the past few weeks so sorry about not having posted for a bit. In this Blog post I wanted to talk about the importance of Virtual Network Adapter Affinity. Here is a screen shot of my configuration below. We have 2 x Mellanox CX-4 Ports one connecting to Top of Rack Switch 1 and the other to SW2. Now what we want to do is bind SMB_1 to Ethernet 5 and SMB_2 to Ethernet 6. One of the neat tricks that I have recently learned is how to...

Hey fellow IT Pro’s in today’s blog post we will look at a super quick and dirty way to download files from your favorite FTP Site. Luckily there is already an FTP Module up in the PowerShell Gallery that we will use for this called PSFTP. Here is your code: install-module PSFTP -Force Import-Module -Name PSFTP $username = "anonymous" $password = "anonymous" $secstr = New-Object -TypeName System.Security.SecureString $password.ToCharArray() | ForEach-Object {$secstr.AppendChar($_)} $cred = new-object -typename System.Management.Automation.PSCredential -argumentlist $username, $secstr Set-FTPConnection -Credentials $Cred -Server ftp://ftp.supermicro.com -Session DownloadingDrivers -UsePassive  $Session = Get-FTPConnection -Session DownloadingDrivers  Get-FTPItem -Session $Session -Path /driver/SATA/Intel_PCH_RAID_Romley_RSTE/Management/5.0.0.2192/IATA_CD.exe -LocalPath "c:\post-install\SuperMicroDrivers" -RecreateFolders -Overwrite Get-FTPItem -Session $Session -Path /driver/VGA/ASPEED/v1.03.zip -LocalPath "c:\post-install\SuperMicroDrivers"...

Deploying Storage Spaces Direct – Part 35 – Did you say #S2D for Free? #MVPHour #StorageSpacesDirect .@MS_Ignite

Eliminating Maintenance Contracts will pay for Storage Spaces Direct! One of the games our industry has played for as long as I have been around, is with maintenance contracts. These contracts are the lifeblood of most of these organizations as they generate run rate revenue well beyond the initial sale. If you don’t read the fine print in your contract most vendors have clauses written into them that allow them to increase the MSRP (Manufacturers Suggested Retail Price) at a reasonable rate each year.

Deploying Storage Spaces Direct – Part 34 – Patching Offline S2D Labs with Cumulative Updates #MVPHour #StorageSpacesDirect

Hey Storage Spaces Direct fans, over the course of the past few months we have been showing you how to build your own S2D environment using PowerShell and scripts like Big_Demo. We have gone almost 6 months now and there are some really critical Windows Updates that need to make their way into your lab. Normally this isn’t that big of an issue as we can setup internet access into the lab and just run Windows Updates or setup a WSUS Server to patch the S2D hosts with Cluster Aware Updating. However, this week I have a situation with...

Deploying Storage Spaces Direct – Part 33 – Is Apple is causing the worldwide DRAM & NAND Shortage? #MVPHour #Apple #StorageSpacesDirect

Hey Storage Spaces Direct fans, I have now had 3 separate customer cases where their Storage Spaces Direct hardware has been severely delayed due to shortages of Flash Memory. This is because the world is moving away from traditional storage “Spinning Rust’ and moving to Flash. This is apparent in almost every Hyper Converged design that I have done over the past 24 months. 100 % of them are all Flash and that isn’t changing anytime soon.   Here is where the rubber is coming off the road for your projects… Lead times are at least 6-10 weeks from...
