info su DL160 e controller P410
devo ordinare questo server, si tratta di questo modello 490454-421
Sto cercando disperatamente ovunque, anche sul supporto HP, qualcuno che mi dica che P410 monta questo server. Mi sono informato anche sulle caratteristiche del controller e ho trovato che il P410 supporta:
RAID 1/0 o 10 senza cache
RAID 1/0/5 o 10/50 con 256Mb di cache
RAID 1/0/5/6 o 10/50/60 con un minimo di 256Mb di cache, BBWC e SAAP
Detto questo, sul sito HP trovo che il DL160 indicato monta il P410 e supporta RAID 1/0/5, quindi dico "bene, ha 256Mb di cache", il sito del fornitore me lo conferma. Faccio cos├м, una prova su un altro fornitore e leggo invece RAID 1/0 e 10. Chiedo sul supporto HP in chat e non mi hanno saputo rispondere. ePrice dice che non ha memoria cache mentre Misco dice che ha 256Mb.
Siccome sto per ordinare qualcosa come 6000тВм di server, vorrei sapere se c'├и qualcuno che pu├▓ risolvere questo mio dilemma. Ovviamente per me ├и FONDAMENTALE che abbia 256Mb di cache anche perch├и vorrei aggiungerci il modulo BBWC a questo controller :-)
Grazie mille a chi mi risponder├а
Un saluto

Re: info su DL160 e controller P410
The P410 is an add-on to this server and uses one of the two PCIe slots.
You can buy the P410 with any option you want. You can have 0MB/256MB/512MB cache and also you can include the BBWC or not.
Which options you buy depends on what perfromance you expect from the server.
The memory cache option helps with the i/o performance of the P410. The BBWC allows you to set up write cache and also allows you to perform online functions such as capacity expansion, raid migration etc.
I suggest, yes, to buy 256MB cache (or 512MB if your budget allows) and include the BBWC option. If you need to do RAID6 or raid6+0 you need the SAAP option.
The P410 quickspecs are here.

Re: info su DL160 e controller P410
thank you for your reply.
This 490454-421 product number have alredy installed a P410 Smart Array Controller, but I want to know wich model it is. I have searched on internet any information about this, but I have found only a mismatched informations. I need to know the CORRECT information. It is a P410 with 256Mb or without memory cache? Can I mount a BBWC cache with this pre-mounted controller? For me is a precious information.
Thank you very much

Re: info su DL160 e controller P410
Thank you for the zero points.
A quick google search for 490454-421 produced this
http://h10010.www1.hp.com/wwpc/uk/en/sm/WF06b/15351-15351-3328412-3328421-3328421-3884343-3919188.html
It clearly mentions
Storage controller P410 Smart Array SAS/SATA RAID 0,1,10, 5
Raid5 meand the controller MUST have 256MB. No mention of RAID6 so NO BBWC.
If you looked on the P410 quick specs in my previous reply, you will see that there are 3 upgrade options
1. BBWC (for the 256MB models)
2. 512MB and BBWC
3. SAAP
Also if I am going to give somebody 6.000 euros for this server I would expect that they should have that detailed information and any other information that I need.

Re: info su DL160 e controller P410
Sorry, but your previous information is not the answer that I expected :)
I think exactly what you've written. If this mentioned controller support RAID 0/1/10 and 5, it MUST to have 256Mb of cache memory. I have written here because HP standard support cannot say to me the correct information about this controller and my reseller say to me "contact HP" :-(

Re: info su DL160 e controller P410
That's unacceptable. The reseller needs to contact HP and get the answer. Otherwise you find another reseller.
