HPE Engineers still suggesting RAID5 for deployments
-
Good morning guys! Just coming off a great weekend! Hope everyone is ok
I spoke with HPE last friday about a new installation I'm doing and one of the engineers wasn't necessarily debating me, but strongly held onto the notion of RAID5 for our scenario for our new installation for our nas and a local server. I explained I have friends in the industry well more versed than I that have had LENGTHY discussions about why NOT to use RAID5 for most of my needs (since its just virtualization and NAS is about all I care about these days) and that RAID10 is usually the best to use depending on certain scenarios.
Is it just me or is it that some people still believe RAID5 is the goto thing in 2016?

Is their RAID 5 true standard RAID 5? That makes a difference. EMC still recommends RAID 5 but it is not your standard run of the mill RAID 5 they have extra protections built into it. The use proactive sparing and already have a certain number of drives duplicated

EMC uses true RAID 5, they just waste tons of money to make it "safe enough" which, in turn, makes it extra expensive and... not a good option. EMC got ripped apart at SpiceWorld several years ago for preaching RAID 5. They were never able to defend it well.

RAID 5 is used to lower the acquisition cost of storage systems so that the vendor can make maximum money on the device and pass the extra risks off to you as the buyer. Vendors believe in RAID 5, yes.
-
Remember, while HPE makes some amazing stuff like 3PAR, they also make "never ever use" devices like the MSA. You would expect people who sell MSAs to also push RAID 5. Once you are working with devices so bad, what difference does the RAID level make? It doesn't make RAID 5 okay, it just makes the whole situation worse.

@krisleslie They weren't quoting all SSD/Flash storage, right?
-
No, still quoting 10K & 15K since its just for Windows Multipoint Server 2012. I refuse to go to 2016 currently.

Why are you looking at external storage for Multipoint servers? 3PAR is massive overkill for that.

Normally I'd say to get your drives from xByte and pay the same for SSD as you do 10K drives. I don't know of a good company that does the same sort of thing with HPE. So I don't know where to go in order to get sanely priced drives that will work in a HPE server.
-
Oh wait, is this HPE Servers, not storage? Why would HPE even get into the discussion of the RAID if this isn't a proprietary storage device? What exactly is being purchased here?
-
SAM yea its just for servers not necessarily external storage. We just plan on using Windows Multipoint Server is small deployments for classrooms which is its best use case. We got on the topic of storage just for the local host, I still plan on having a local NAS and then site to site back up via rsync.
Of course he got on the topic of external storage and I immediately let em know I got a synology nas with raid 10 works fine I leave it alone lol

Gotcha. Why is there then an HPE Engineer involved at all? Remove him from the conversation. He's a vendor and not on your side. He's trying to sell servers, not protect you. RAID 5 isn't an option there. RAID 6 and RAID 10 are. Or even RAID 1 in some cases.
HPE should not even be having a conversation with you like this. You tell them what parts to ship, they ship them. End of engagement. Don't let their sales guys pressure you. And don't let them have any insight into the RAID, that's not for them to know about.

No pressure so far but I know if I let the engineer have his way lol it would come at some point. Knowledgeable guy! I'm interested also in getting a relationship with them locally (as well with Dell) just for the philanthropic side of it.
-
Oh I forgot to mention this SAM, I told him about you and he wanted me to send him some of your articles and I said I sure GLADLY WILL
He really wants to sell me on buying a dual server setup (which I might) just not because of his reasoning.
I explained that really sticking with a single server and beefing it up and having the things that break on site is really the best cost/case scenario. At that point he brought out the "what if the motherboard breaks" chat and I said in a case like that, thats where the 4 hour or NBD would come into play, but I would still have a good plan in place to limit/mitigate complete failure.

Well, BUT... the engineer only sets up the box to ship. You ALWAYS start from scratch once it arrives. So even if he sets it up as RAID 5, you'd never know because you ALWAYS without any exception, set up your server yourself once it arrives assuming that nothing has been done.
But why is an engineer even talking to you? I'm confused by how the scenario arose.
-
Well the engineer came at the request of the sales rep not me.

This is an odd tact that I've seen a few times from HPE.... trying to sell you more gear by telling you that their products are bad. It's crazy. Basically he's trying to scare you by putting the notion into your head that HPE can't fix your server if it breaks. Um, if so, why am I buying HPE?

Why is the sales rep getting to make choices like that?
-
Coincidentally, I talked to my dell rep and engineer and we all got along quite nicely. We have a spec in place and I should start testing with them this week or next.
-
The sales rep eventually got quiet, I actually think the sales rep wanted to be in favor of me, but the engineer kinda took the wheel. He wants me to go full VDI. I don't want full VDI.
