VMware's user groups fuming again, consider deposing leaders

Equals42

Re: Is it Possilbe this is a good thing???

>It sounds like VMUG won't lose anything.

Umm, independence and a VMware focus?

>This would have happened anyway, so I'm glad the VMUG is leading it.

Why is it inevitable? Why couldn't these remain what they were: a useful place for VMwae admins and others to gather and discuss VMware products, exchange ideas, share horror stories, and get some occasional assorted vendor SWAG and beer?

>It isn't feasible for EVERY member to make EVERY decision- not for a $15M organization with 150000 members.

This wasn't a plebiscite, nor was that requested. Not even the heads of VMUG standing groups or others deeply involved were consulted. You don't need to get everyone's permission but you should run it by the day to day leaders of the organization.

This makes it less likely that members will get to hear from Veeam, Nutanix, IBM, Cisco, HPE, HDS, NetApp, Commvault, etc. How is that good for everyone? It's not like everyone runs VMware only on Dell servers and network. Heck they already booted the Nutanix folks which were very involved and useful because they weren't towing the DellEMC line. If they want to have meetings to sell Dell equipment, they should rent a steakhouse like they always did and feed a bunch of admins/architects while they stare at the Powerpoint slides.

Sweet AFA: Pure sees flash of Big Blue as it drops to fifth behind IBM

Equals42

Re: Does AFA matter?

"There is a big difference in architecture and how systems handle flash when it's built from the ground up for that purpose."

Really? What part of it did they build from the ground up? Let's see:

1980s SCSI command set? Not until NVMe over fabrics is in the wild. Until then you're speaking SCSI.

Intel CPUs and DRAM? Nope. Same stuff in all the arrays except special ASICs from 3Par which are always late to the party... makes nice slides though.

Fibre Channel? Nope. Still works. Cisco and Brocade are pushing 32g FC for NVMe over Fabric.

Ethernet/FCoE/NFS/SMB? Nope. Not invented new for AFA.

Inline Compression/Dedupe? A lot of the AFA have those whether built from the ground up or not.

Scale out? Well that's not really an AFA feature and many of them fail that one.

Simple GUI or admin? Simplicity is nice until you need a feature. I agree some platforms are too complicated. It's a feature though not intrinsically tied to AFA.

SSDs or CFM? Most of them use SSDs and they should. My money's on SSDs. Going your own way on chips hasn't worked on for a long time. See Sun, DEC, SGI... Heck, the chipset landscape is cleared of competition. Where's Adaptec, AMI, LSI, National Semi...

Really it's just a storage array tuned for much faster backend access. It gives the manufacturers some new ability to tune their stacks instead of waiting for spinning rust to respond and lessen the need to buffer as much. There's great advances possible in AFAs but it's still just faster storage until we change the protocol. Even then, it's just faster. It's still retrieving the same old bits faster; not adding chocolate flavor to your bytes.

Does faster storage effect other things in the compute stack? Sure does. That still doesn't mean that it's fundamentally different from another array other than speed and with a neat bezel.

NetApp confirms: SolidFire hyperconverged appliance is coming

Equals42

Re: Product margin!

First, I may be old enough to be your grandfather. Second, product margin is only part of the whole story. Pure states a 63% product margin (down 3% YOY). If you think Pure is making a dime of profit even with their 63% product margin vs NTAP's 46% you'd be daft. Support and services are high margin. Anything wrong with that? They count too as long as new sales aren't tanking. Take the whole picture into account.

Re: Product margin!

That's nonsense, troll. NTAP has in their Q3 results:

60.8% Gross Profit Margin

8.9% Operating Profit Margin

NTAP are profitable. Can you say that about their competition? Pure and Nutanix are still losing money on every sale. Violin is kaput. Who knows about Dell/EMC - we have to wait until they emerge from their layoffs and engineering/product line purge. IBM is shedding product lines. HPE was one of two life boats off that sinking ship. HDS hasn't really got it together yet. Oracle...

Among a sector which is suffering a large transformation, NTAP is doing fairly well as the analyst said.

This many standards is dumb: Decoding 25Gb Ethernet and beyond

Equals42

Let's see if I remember this correctly. I think the previous poster is referring to the problem in iSCSI when you either have MPIO on the host aggregating multiple links or when you setup LACP on the host to a switch. In both cases, the host is exposing those as a single logical path even though the underlying paths are still separate below that level. Take a 20g LACP of two 10g paths. Any one iSCSI session can only actually get 10g of bandwidth because the aggregation doesn't actually bond the physical layer (or was it Layer 2?) to give you a 20g path. It only gives you a single logical path that masks the two separate 10g paths. That single iSCSI stream will saturate the chosen path at 10g. LACP and MPIO do that for good reasons and generally behave like a 20g path except in some cases like iSCSI sessions.

The new 100g and 40g solutions they describe do not evidence that behavior because that single iSCSI session would be multiplexed across all those individual channels and recomposed at the other end unbeknownst to the iSCSI protocol. They will act as a single path with their combined speeds.

Can all-flash arrays, spinning disks and hybrid really live together?

Equals42

Wow! This is riddled with inaccuracies

This is a huge load of stupid.

"Every byte of flash storage that you buy from a hybrid vendor is more expensive than the same amount in an all-flash array, he argued.".

Based on what evidence? Just dropped there like there was an IDC report with that as the title. So only companies that don't sell spinning rust can discount SSDs?

"Customers might want to use all-flash arrays as the primary system, and then send snapshots from that system to a hybrid one. In the real world, that’s not really possible, he says. It would take a lot of technical work to make it happen."

That's just weirdly wrong. Does that person quoted actually have experience with SAN arrays? You can do that in the NetApp array he dismisses earlier in the story quite easily. I know lot of clients who do. It's not a special feature. EMC can replicate from flash to spinning even if you have to use RecoverPoint. It took 10 seconds to Google how to replicate from XtremIO to Vmax or VNX.

Just terribly stupid writing.

Brexit may not mean Brexit at all: UK.gov loses Article 50 lawsuit

Equals42

"This is your decision. The government will implement what you decide," a pamphlet issued by the government at the time said.

That's basically saying: the current controlling party promises to try to implement solution the majority of voters decide.

However, they should have to have a vote of Parliament to push through a change of the legal structure of the whole country. Seems absurd that they'd be able to by fiat just wipe out all the regulations by which the country runs without Parliament agreeing on the record.

As a US citizen it also seems strange to make such a huge change by simple majority. Parliament and all other political and legal decisions are made using representative voting. Every U.K. election I watch from afar amazes me in that the left parties generally get far more cumulative votes that conservatives but the Tories somehow skate away with a majority in Parliament. Everyone seems ok with that but then a 2% majority of the 72% who voted is enough to scrap 40+ years of legal progress by numerous elected Parliaments? Very strange.

NetApp, storage class memory and hyper-convergence

Equals42

Your analogy sucks. Photography industry is still doing fine selling cameras, lenses, and other associated equipment. Film companies died. The market changed but optics didn't change because the recording medium changed.

What you do with any medium matters greatly. You can easily make a platform with SCM and it can suck. Really suck. I think you have misunderstandings on how many engineered products work.

QLC flash is tricky stuff to make and use, so here's a primer

Equals42

Re: And then spinning rust

The power and space savings of 60 and 100TB 3.5" flash is hard to beat with spinning rust. I have an affinity with it as well having spent some time up on the hill above Almaden Valley where a lot of good research was done. However, >1 watt at idle vs 8 watts is huge especially when you have to have 10 or more spinning disks to get the same capacity. That's nearly 2RU in a typical 12 disk per 2RU config (though I know you can get denser) and 80 watts vs ONE 3.5' drive and <1 watt for your typical archive storage where it should be idle quite a bit. Even when busy you save power just not as dramatically. Add in the crap durability of SMR and I don't see how spinning disk even competes going forward. if your needs are more in the speed and capabilities range, then MLC is your buddy.

I'm not going to argue about tunneling vs arcing. Call it what you want. It works and is proven. You worried about arcing while you fill your tank at the gas/petrol station and read email?

Confused as to WTF is happening with Apple, the FBI and a killer's iPhone? Let's fix that

Equals42

More than just this one example at stake

Just remember that while courts in the US may say that they'll only use this in extreme cases (I don't buy that) there are plenty of countries where I'm sure they aren't as squeamish about stomping on privacy rights. This privacy protection extends to a great number of people who live around the world. If every country can force Apple to do this or face losing access to their market, it basically means that Apple would have to either dedicate a whole crap load of people to do this full time or they might as well give up on giving people the appearance of privacy.

NetApp sings to Solidfire: All I want for Christmas is buying you

Equals42

Feed the troll I guess. This simply validates that FlashRay was a mistake. AFF and cDOT are still excellent products in their market segments. Good to see NetApp isn't too hardheaded to change direction when they fail.

All in all, a good thing for the market if SolidFire is a good product since it will now have financial and distribution legs to keep progressing. I haven't had personal experience with it.

Fujitsu waves 50PB+ MONSTER at hyperscale storage freaks

Equals42

Re: Where's the corresponding tape silo?

These systems have replicas and for serious outfits they have multiple geographies with rules in place to make sure there are always replicas in multiple geographies. If the burly men can be in several places with sledgehammers and transit vans, you are in big enough trouble that backups aren't a concern. A good lawyer or a fake passport are in order.

Re: I don't geddit.

@ratfox - or have an open system of relays which do not depend on any single person/corporation to hold the data or make the rules. We used to have this in NNTP and usenet but eventually bots, spammers and dumbasses made it too hard to find anything useful and ISPs no longer offered it is a service so you had to find a public source.

Storage management tools SUCK. We're getting what we pay for

Equals42

Re: out of interest...

NetApp has virtual editions of both their FAS line (7mode and clustered) and the Eseries. They are downloadable from the support site. Hitachi had a virtual VSP program that I had a copy of but I haven't looked recently. Other people pointed out the EMC emulators.

All of them are great ways to try out the interfaces for different vendors. It's also a great way to test out scripts or orchestration flows without borking your real SAN.

HDS software has nearly universally sucked forever. (I'm sure that'll register as a terrible example of grammar on any side of the Atlantic.) The 9900/USP/USPV/VSP are all rock-solid boxes that are a pain to configure but then run forever. There have been promises of better software for years and while they are better now they don't compare to the engineering found in the arrays they monitor and manage.

REVEALED: What you'll pay for VSAN software and hardware

Equals42

Do you think those CPUs in storage arrays are there just to help keep the HBAs cozy and warm? It takes compute power to run a real array and host IO directed at it and probably more so for a virtual array. There's no free lunch! You'll have to take your existing compute needs and then add the storage load onto that. You aren't going to be able to squeeze VSAN into an already fully loaded compute farm. You can try, but you'd better have your resume freshened up first or a forgiving manager with the Dell rep's number on speed dial.

Cloud buyers: Why it makes sense to think local

Equals42

Re: Dynamic provisioning

The majority of companies have similar daily/weekly io usage patterns. The cloud providers have to build based on peak usage. A bit like highways. Not everyone works 8-5 but enough do that the highways are built to accommodate that. You'll be paying for cloud providers to overbuild as well. Just like the rest of the IT world does. No free lunches.

In spinning rust we TRUST: HGST slips out screamingly fast ... HDD

Need another source

Big players in storage generally require dual sources for drives. Until another 2.5inch 600g 15k rpm drive comes around from another source I don't expect to see a shelf of them on many vendors' price lists.

NetApp shows off tech specs of FAS array BIZ BEAST

Equals42

Re: what, more hardware on a monolithic processing scheme?

You are apparently misinformed. NetApp has been breaking out processes from Kahuna for years to get better use of cores. In my experience, almost every 8.x release has been a bit better in utilizing cores. Perhaps you're thinking of VNX2 which finally uses those multicore procs unlike the VNX they sold people as recently as August.

NetApp has had synchronous replication for years in 7-mode.

EMC's ViPR is great ... for other vendors, at least

Equals42

This sounds like it will make it easier for EMC's frenemy Cisco to bring the EMC stack further into Cloupia. Why would you want to automate the storage stack when you can bring it into the whole stack? I also heard mention of management but what of measurement and reporting? Will performance and reporting APIs for EMCs wide array of products be exposed so third parties won't need a proxy?

I get there's the file/object aspect of ViPR but that might be exposed by Openstack anyway won't it? It seems like EMC saw itself being painted into a corner with their many closed APIs and figured they'd have to open up to play in the new private cloud datacenter so they might as well productize it. Hence ViPR.

Everyone else who isn't already open with their APIs is probably thinking the same thing but EMC likes to pre-announce products far ahead of reality so they look visionary.
