One Of My customers wants to buy a new storage, he asks me to compare the HP EVA 4400 with similar products from EMC and Netapp..
i found that the EMC CLARiiON CX3 Model 20 & NetApp FAS2050 Storages in the same level with EVA 4400..
I want you to advice me , what is the killing points in EVA 4400 (which is not in other storages ) ,with it i can
Convince the customer to be sure to go to HP EVA 4400 instead of EMC or NetApp...?
Solved! Go to Solution.

here you can find some marketing stuff:
a) video on testing the EVA4400 against the Clariion CX3-10:

b) EVA/Clarrion/Netapp TCO white paper:

Re: HP EVA4400 & EMC CLARiiON CX3 Model 20 & NetApp FAS2050 Storages
I often worked with different CX storages and I hate them... If you delete and re-create a lun multiple times you need to destroy and re-create the whole raid group again, because there is not enough space in one peace to create a lun. The raid level of the raid group applies to all luns in the raid group. This is likewise to the MSA2000. The CX3 is like a MSA2000 with fibre-backend. You can't mix ATA and FC drive in a shelf. You need new shelfs if you want to use ATA drives.
The filer is more a NAS than a storage. I wouldn't compare a FAS2050 to an EVA. Surly you can use FC oder iSCSI block-based storage from NetApp, but luns are still container files in the WAFL (the filesystem of a filer). If you want to use snapshots you need to reserve space. NetApp is still using RAID 4 and a RAID 4 with two parity disks, called RAID DP. They use some nice tricks in the cache to speed this raid level up. Filer are great NAS, but terrible block-based storage systems.
The virtualization features of a EVA is still leading. You can mix FATA and FC drives in one enclosure. You can create vdisks with different raid levels in one disk group. You don't need spare drives, because free space in a disk group is used for rebuild, or reserved spare (disk protection level) over all disks in a disk group.
Tell your customer that he should compare the CX and the NetApp to an MSA2000. The silver bullets of the EVA are
- VRAID
- mix disks in one enclosure
- performance
- scalability (maybe not true for the EVA4400, it only scales up to 56 disks)
Hope this helps.
Best regards,
Patrick
