    Appreciate the perspective you have about 3PAR. I agree that there are some real issues with vVOLs in the short term - no question. Replication is a deal breaker and that cascades into things like vMCS or SRM. It's a 1.0 implementation and it will get better. Once vVOLs has that, the playing...

    So we can agree that we don't have the same definition of "traditional array" and I will continue to assert that 3PAR isn't one. Good to have the perspective DontPanic! shared. We'll continue to talk about 3PAR as non-traditional. Does Tintri support non-virtualized environments? Guessing...

    Backup NAS, FreeNAS and transfer of data

    I'm active on Spiceworks where a lot of customers are building DIY NAS. FreeNAS gets clobbered by people in Spiceworks. If you're looking for free, FreeBSD seems to be the NAS of choice there. Here's a link that might be helpful to look at options...

    I don't know enough about Tintri to give you an honest assessment. They are a VMware only platform. I think with the emergence of vVOLs, a lot of the advantages Tintri had (of granular control of VM storage) go away. I've seen Tintri spending a lot of time bashing vVOLs and that can only mean...

    3PAR allows you to scale up and out. You can start with a 2-node entry array and the family scales up to 8 nodes. So yes, the capacity of those systems grows as nodes are added. A key concept with HP 3PAR is that it stripes data across the entire array. With a traditional array, you pick a...

    Actually, 3PAR is not at all a traditional array. The guys that designed it based the controller architecture on server clustering. It uses a custom ASIC that drives a lot of the value: Internode communication: 3PAR is very different from other traditional 2 controller arrays. It scales to...

    All-flash is taking off so the marketing folks lead with talking about all-flash. You can get an all HDD HP 3PAR StoreServ 8200 too (the previous generation 7200 is still available too). The 7000 and 20000 3PAR families have been updated to the 8000 and 20000. An 7200/8200 means max two nodes...

    That's a great compliment (about not pulling an equallogic or compellent). No doubt equallogic was THE iSCSI leader back when Dell bought them. But because of their architecture, they're stuck at a dead end. Compellent is definitely interesting tech but Dell trying to position it as enterprise...

    I keep meaning to do a blog post talking about what we've done with LeftHand (StoreVirtual) over the last few years. It's had more than it's share of updates - hardware has been updated to ProLiant Gen9, added sub-LUN tiering, 2 node quorum (with an NFS file share), and a lot more. It's a solid...

    We can do something called a Flat SAN which will connect 3PAR to BladeSystem via virtual connect) without a FC switch but I'm 99.9% sure there's no SAS connect. The StoreVirtual 4530 sits between the MSA and 3PAR. Really does somethings well. Not sure if you have heard of LeftHand Networks...

    Sorry, I missed the replies to I'm late! I guess we should define traditional platform but I'd say that 3PAR isn't traditional. A "traditional" dual controller (usually active/passive) is traditional. HP 3PAR uses a mesh active architecture for a shared everything fine-grained...

    MSA's aren't bad but the MSA's in use are pretty old. I"m obviously biased (I work for HP Storage) but HP 3PAR is some of the best storage out there for virtualization and IaaS. Lots of service provides are using 3PAR. 3PAR was in fact the exclusive FC development platform that VMware used...

    3PAR Raid Sets

    Sorry for the multiple "answers" to this. I asked one of my storage architects to help me give a better answer (beyond what is in the best practices guide). Here's what I got: The rule of thumb for best practice is to configure things so that the number of enclosures behind a node pair can...

    3PAR Raid Sets

    RAID 6+2 doesn't mean two spares - it means 6 data and 2 parity drives. 3PAR is very different from a traditional RAID so the normal "what I've done with traditional RAID" could lead you down the wrong path.

    3PAR Raid Sets

    DISCLOSURE: I work for HP Storage. One point that I think is missing with the hot spare conversation is how HP 3PAR uses spares. There isn't a drive that is flagged as spare and sits there idle waiting for a failure. Because 3PAR uses fine grain virtualization to spread data across all drives...
