For Changing maximum queue depth settings in Emulex HBA on servers running RHEL 6 loading and unloading lpfc module is needed. By default most cards default to a queue depth of 32 which is perfect for a general purpose server and prevents the SAN from getting too busy. How do I query the HBA drivers to verify that the correct driver parameters have been successfully loaded and applied?. The Queue Depth setting on the HBA will specify how many exchanges can be sent to a LUN at one time. On Windows hosts, you can use the LPUTILNT utility to update the queue depth for Emulex HBAs and the SANsurfer HBA manager utility to update the queue depths for Qlogic HBAs. 1 and Windows Server 2012 R2 , the DFSRS. Dec 15, 2013 I am sorry. Step-by-Step, "how to" configure Hurricane Batch Script Generator for AutoCAD. Select Ease of Access > Narrator. The only supported guest operating systems for virtual fibre channel at this point are Windows Server 2008, Windows Server 2008 R2, and Windows Server 2102. Additional Documentation. 1, 32-bit and 64-bit Windows 2003 Server 32-bit, SP1 and higher, print and scan drivers only Windows 2003 Server 64-bit, SP1 and higher, print driver only by using Add Printer Wizard Windows 2003 Server. Identifying the firmware model and driver for HBA on esxi host Where #### is the model of the Qlogic HBA 0 Total number of interrupts = 14 Device queue depth. SchedNumReqOutstanding' set to 16. Solved: hi how do I change the queue depth for an esxi host in 5. Re: How to view FC HBA Queue Depth? Denny, I donâ t know about 2462, but with 23xx cards I remember we can get into Qlogic Card BIOS while booting (by pressing F8 I guess) and you should be able to see a parameter under advanced settings called as "Execution Throttle". • Root Cause: For Raw devices, the maximum supported queue depth was always set to 256, which results in sequential I/O's not being coalesced. For SAS targets, it is set to 64 and for SATA it is set to 32. Basic UNIX commands Note: not all of these are actually part of UNIX itself, and you may not find them on all UNIX machines.

Hitachi said: Please check the lun queue depth settings on the Citrix server these need to be set to 32 divided by the number of active host paths to the luns All hos. IO Queue Depth Strategy. Tape manufacturers recommend a Queue depth less than 8. By 1802 wearing a queue was a regulation in the British army, but by the mid-19th century queues had disappeared along with cocked. Lower costs, and it's a simpler device (that is more stable as there is less code on the HBA package than something that has a lot larger firmware package). If the SLA for the application is to get the latency level below 5 msec then Queue Solver completes its analysis and recommends that queue depth be set to 22 and 24. Our programs train the next generation of innovators to solve real-world problems and improve the way people live and work. Note that in the likely reduced resolution and color depth of a VNC window the full desktop will be rather cramped and a look bit odd. The VMware DSA course also notes that the SchedNumReqOutstanding limit only apples when there is more than one VM per LUN. Because the LUNs of this host were migrated from a EMC array, I suspect this setting to be sub-optimal. The thinking here is that the VMkernel driver module ultimately controls the HBA's queue depth. 28 lb) Shipping dimensions and weight (approximate): Height: 48 mm (1. " Data were… Weather. Only the LISTSERV maintainer can create a super-list, for security reasons. To identify the storage adapter queue depth: Run the esxtop command in the service console of the ESX host or the ESXi shell (Tech Support mode). 2017 • FlashArray NVMe • VMware • Virtualization • by codyhosterman So I am in the middle of updating my best practices guide for vSphere on FlashArray and one of the topics I am looking into providing better guidance around is ESXi queue management. The fact-checkers, whose work is more and more important for those who prefer facts over lies, police the line between fact and falsehood on a day-to-day basis, and do a great job. Today, my small contribution is to pass along a very good overview that reflects on one of Trump’s favorite overarching falsehoods. Namely: Trump describes an America in which everything was going down the tubes under  Obama, which is why we needed Trump to make America great again. And he claims that this project has come to fruition, with America setting records for prosperity under his leadership and guidance. “Obama bad; Trump good” is pretty much his analysis in all areas and measurement of U.S. activity, especially economically. Even if this were true, it would reflect poorly on Trump’s character, but it has the added problem of being false, a big lie made up of many small ones. Personally, I don’t assume that all economic measurements directly reflect the leadership of whoever occupies the Oval Office, nor am I smart enough to figure out what causes what in the economy. But the idea that presidents get the credit or the blame for the economy during their tenure is a political fact of life. Trump, in his adorable, immodest mendacity, not only claims credit for everything good that happens in the economy, but tells people, literally and specifically, that they have to vote for him even if they hate him, because without his guidance, their 401(k) accounts “will go down the tubes.” That would be offensive even if it were true, but it is utterly false. The stock market has been on a 10-year run of steady gains that began in 2009, the year Barack Obama was inaugurated. But why would anyone care about that? It’s only an unarguable, stubborn fact. Still, speaking of facts, there are so many measurements and indicators of how the economy is doing, that those not committed to an honest investigation can find evidence for whatever they want to believe. Trump and his most committed followers want to believe that everything was terrible under Barack Obama and great under Trump. That’s baloney. Anyone who believes that believes something false. And a series of charts and graphs published Monday in the Washington Post and explained by Economics Correspondent Heather Long provides the data that tells the tale. The details are complicated. Click through to the link above and you’ll learn much. But the overview is pretty simply this: The U.S. economy had a major meltdown in the last year of the George W. Bush presidency. Again, I’m not smart enough to know how much of this was Bush’s “fault.” But he had been in office for six years when the trouble started. So, if it’s ever reasonable to hold a president accountable for the performance of the economy, the timeline is bad for Bush. GDP growth went negative. Job growth fell sharply and then went negative. Median household income shrank. The Dow Jones Industrial Average dropped by more than 5,000 points! U.S. manufacturing output plunged, as did average home values, as did average hourly wages, as did measures of consumer confidence and most other indicators of economic health. (Backup for that is contained in the Post piece I linked to above.) Barack Obama inherited that mess of falling numbers, which continued during his first year in office, 2009, as he put in place policies designed to turn it around. By 2010, Obama’s second year, pretty much all of the negative numbers had turned positive. By the time Obama was up for reelection in 2012, all of them were headed in the right direction, which is certainly among the reasons voters gave him a second term by a solid (not landslide) margin. Basically, all of those good numbers continued throughout the second Obama term. The U.S. GDP, probably the single best measure of how the economy is doing, grew by 2.9 percent in 2015, which was Obama’s seventh year in office and was the best GDP growth number since before the crash of the late Bush years. GDP growth slowed to 1.6 percent in 2016, which may have been among the indicators that supported Trump’s campaign-year argument that everything was going to hell and only he could fix it. During the first year of Trump, GDP growth grew to 2.4 percent, which is decent but not great and anyway, a reasonable person would acknowledge that — to the degree that economic performance is to the credit or blame of the president — the performance in the first year of a new president is a mixture of the old and new policies. In Trump’s second year, 2018, the GDP grew 2.9 percent, equaling Obama’s best year, and so far in 2019, the growth rate has fallen to 2.1 percent, a mediocre number and a decline for which Trump presumably accepts no responsibility and blames either Nancy Pelosi, Ilhan Omar or, if he can swing it, Barack Obama. I suppose it’s natural for a president to want to take credit for everything good that happens on his (or someday her) watch, but not the blame for anything bad. Trump is more blatant about this than most. If we judge by his bad but remarkably steady approval ratings (today, according to the average maintained by 538.com, it’s 41.9 approval/ 53.7 disapproval) the pretty-good economy is not winning him new supporters, nor is his constant exaggeration of his accomplishments costing him many old ones). I already offered it above, but the full Washington Post workup of these numbers, and commentary/explanation by economics correspondent Heather Long, are here. On a related matter, if you care about what used to be called fiscal conservatism, which is the belief that federal debt and deficit matter, here’s a New York Times analysis, based on Congressional Budget Office data, suggesting that the annual budget deficit (that’s the amount the government borrows every year reflecting that amount by which federal spending exceeds revenues) which fell steadily during the Obama years, from a peak of $1.4 trillion at the beginning of the Obama administration, to $585 billion in 2016 (Obama’s last year in office), will be back up to $960 billion this fiscal year, and back over $1 trillion in 2020. (Here’s the New York Times piece detailing those numbers.) Trump is currently floating various tax cuts for the rich and the poor that will presumably worsen those projections, if passed. As the Times piece reported:
