Some things with SVC that VPLEX doesn't have: Thin provisioning Write cache Easy tier (automatic better performing storage) Advanced features (mirroring, snapshots) can be done across different back end third party arrays This guy tries to defend the VPLEX but most of his points are weak, or trivia. If you have hosts accessing the same data in multiple active data centers then that might be an argument for VPLEX, but SVC can do that too. SVC is easy to manage as well with the new GUI, and has real-time compression built in. http://vchetu.blogspot.com/2012/07/emc-vplex-vs-ibm-svc.html another comparison, note that you *can* encapsulate LUNs with SVC Image Mode. Full disclosure: I work for IBM and have sold several SVCs.

Been a long time since I did networking... buuuttt... route add default public.81.1 1 should the trailing 1 be ntapifgrp01 or ela ? Even so you should still be able to ping the default gateway. Can you ping the gateway from another host, and ping all the filer's IPs?

Why wouldn't the VMs write to the storage at site A? I don't understand your concern here. Snapview (as part of Mirrorview/A) is pretty crappy but in theory this should work.

sanchez posted:A client has an EMC vnxe 3150 with a couple of SAS shelves attached, and a total of about 22 300gb SAS drives installed. When he originally set it up, following EMC's advice, every drive (minus hotspares) has been added to a single RAID 5 array. Since it's not in production yet we advised they move to RAID 10 instead (space will still be fine) mainly because I'm worried about rebuild times on an array that large along with redundancy in general. Is this rational? I would set up 1 hot spare and three RAID 5 6+1 groups. If you have 1-2 hot spares and the rest is all a single RAID 5 group, that's not a good idea. RAID 10 would be if you need high performance or high redundancy.

bull3964 posted:Just out of curiosity, why is RAID 5 instead of RAID 6? I'm not sure I would be comfortable with single parity in a production setting, even if you did have a hot spare. RAID 6 is an option if you want to do two 8+2 groups and two hot spares. Slightly more capacity at somewhat lower performance. If you want more redundancy, sure, do RAID 6 or 10. I'd advise not using RAID 5 on 1TB and above drives, or SATA. It's all about what your requirements are, though for 300GB drives RAID 5 is pretty standard.

What's the distance between the sites? If you do synchronous replication it may impact the performance of your applications if the distance is large. And if the distance is more than 180km (300km for some IBM replication), it isn't practical or possible. The latency just gets too high for your host application.

We've sent IBM a list of questions about how the Lenovo deal will affect our support and future products, but no response yet. From what I know, GPFS and SONAS will still be IBM.

KillHour posted:Secondly, while most of the systems will be 20TB or less (which I could shove in a DL380 12-bay, no problem), we will probably need to accommodate systems as large as 200TB or more. I could either go with external DAS units or use something like the Proliant 1xSL4540 to get the job done. Is there a good reason to go with one over the other other than cost and rack density? What is the densest system out there outside of SANs? I know Supermicro has a 72 LFF disk system, and I've seen them advertise a 90 LFF disk system (but I can't find it on their website, is it new?). For the higher end arrays (200-300TB+), 15k drives are being priced out, squeezed on both ends by 10k and SSD. Milestone video surveillance for casinos  uses two tiers with 7.2k the pretty optimal choice for the lower. The questions are do your customers require the extra throughput of SSD over 10k drives, and can they afford the additional cost? In my experience the answers are "no" and "no". However, SSD prices are coming down all the time, so YMMV.

I've worked with the Flashsystem 900, some of my customers are getting 900s and v9000s. The 840 is a good bit nicer than the 820 all around, modular, nicer GUI, easier upgrades. The 900 is not drastically different than the 840, primarily it has more capacity.

Kaddish posted:Can you virtualize storage on a v9000 just like an SVC/v7000? It looks like they literally stuffed an SVC pair in there. If yes this may not be a bad option..... Yes, the v9000 is basically an SVC DH8 node pair connected to a Flashsystem 900. It's slightly more complex than that but that's the idea. You could put a v7000 in front of a 900, or flip it around and put a v9000 in front of a v5000 if you needed more processing power (since the DH8 nodes are more powerful than the v7000 gen2 controllers). http://www.redbooks.ibm.com/technotes/tips1281.pdf

1. Hypothetically yes, you can get 32gb aggregated over four ports. It is likely that your bottleneck will be something other than your switch and HBA ports. Use multiple hosts connected to all ports and using multipathing. Controllers have multiple ports for bandwidth and for redundancy in case of component failure. 2. Your question is unclear... is the 4gb switch powered by the c7000? Is it a passthru switch or a fabric? Connected to blade servers in the c7000? First page of what? Exception to what? I think the answer is yes but the more I read what you wrote the more confused I get. 3. It sounds like this is an MDS powered by the c7000? If so you could connect the switch to an external SAN switch if you needed more ports for your fabric. I would keep it simple if you don't actually need that. 4. Whatever works for you.

I've only done this with Brocade but it should work similarly with cisco. If you attach an inter-switch link from your existing switch to a new one (without a config), it should download the config from the existing switch. Then you can migrate all your ports over to the new switch leisurely, disconnect the ISL once complete, and retire the existing switch. You could download the config from the existing switch to a text file and upload it to the new one... I think that would work. This link describes how to do it though it's not specific, maybe google around some more for specific instructions on downloading/uploading a config to a remote server. https://www.cisco.com/en/US/docs/storage/san_switches/mds9000/sw/san-os/quick/guide/quick_cg.html obviously check and test this before relying on some random internet jackasses' word.

CommieGIR posted:Well, since no one knows, Im just gonna jump on this v7000 and see what I can do Well if you want my opinion, it seems overkill. I'm assuming someone surplused it to you? Upgrade the code before the swma ends. Best home config is probably iscsi with DRAID 6 on the back end. No clue if it would accept untested drives, but since it's probably out of warranty you could try.
