Hitachi 9570V or Storagetek D240?
I've been put in charge of evaluating the above mentioned system
proposed by vendors for our SAN implementation and is undecided between the 2 System. The Hitachi 9570V specifications are very impressive, 32 TB Maximum raw capacity with Maximum Cache of 4 GB. The HDS system has 4 FC host port and 4 FC/AL for connection to additional enclosure and i have no doubt with Hitachi's hardware performance at this point. I was offered a 1.1 TB raw storage and 1 GB cache for each DP600 FC controller to start with. On the software side, Hitachi does not include Snapshot feature with Storagetek offered with their SANtricity software. And from my point of view, their UI is not as user friendly as that of SANtricity's. However, one good thing is that they've offered Preemptive maintenance with their Hi-Track program which is included in the deal. Hi-track Dials back to HDS for the system monitoring everyday and initials Preventive maintenance on the system. Storagetek offered me the D220 from the start and upon knowing HDS offers the 9570V, they came back with a quote on D240 with 1 TB raw storage and 1 GB cache for each storage controller(LSI's 2882). 4X2Gbps host side FC port and 2 FC/AL for drive expansion. Hardware wise, there's nothing flattering as compared to the HDS systems. They refused to share with me their controller architecture but on surfing the LSI's mainpage, i've found that their architecture has nothing to boast about. It's the same design that all over vendors had been pursueing for the past decade. It's tried and tested but they might have system bottleneck once capacity reaches the bounds of 10+ TB. The architecture describes that hosts connected to FC hubs connects to a pair of Controller side FC interface chip which no numbers have been published. HDS openly publishes their system bandwidth of 4.5 GB/s. However, after searching high and low for Storagetek's numbers, i've only managed to find that IBM's FastT700 which is OEMed from LSI with a higher end controller model, 4884, is only running at 2GB/s from the Evaluator Group report. Storagetek's Software package deal however includes Multipath/IO and Internal snapshot program which i would have to purchase separately from the HDS deal. I'm not also not comfortable with Storagetek's presence in my country as they are only a 30 man company compared with HDS presence in this part of the world. I'm also worried that Hitachi might charge of premium for subsequent year maintenance for the system and future storage addition. Hitachi offered a 1 year only program for their Hi-track service and a 1 year hardware warranty whereas Storagetek has their standard 3 year warranty. Price are very competitive between the 2 vendors with around USD$250 between the 2 vendors(Storagetek the has the lower bid. Thank you for reading this post. I hope you guys out there can offer me your opinion on this 2 systems. |

Thank you for reading this post. I hope you guys out there can offer me your opinion on this 2 systems. Both systems are fine, but it would really help if you tell what you intend to use them for. Having snapshot is great, but if you're not going to use it then it's not a gating factor. Will the system hold databases or video streams? Big difference... Tell us what you are planning to do with the system, maybe we can help you better. Money-wise, 250$ difference is no difference at all. You probably need a consultant to set some of this up, the difference is equal to offering him a coffee break.. Rob |

We intend to consolidate every of our data storage requirement into this box. Email (exchange databases), NAS head attaching to it for File level access, microscope pictures which are large(typically 100MB-1GB) for analysis research on Nano materials etc. Pictures had been estimated to grow to 4TB. We are planning to use Sharepoint portal to provide interface consolidation with all applications.(Sharepoint uses MS-SQL). Exchange 2003 clusters and Windows Storage Server 2003(WSS2003) clusters are also in the pipeline. WSS2003 has Volume shadow copy service (providing 255 snapshots). I preferred this as users will do their own retrieval of versions of that file directly without administrator's intervention to mount the backup volume. The box is not expected to reach anywhere in 10+ TB for the next 2 years. This is a pure windows shop but we don't rule out any other platform in the future. Anyone had problems with LSI's SANshare with Microsoft's clusters? Anyone ran Exchange 2003 on active-active cluster(each running separate Information store on the LSI ware? Anyone had experiences with HDS and MS's Clusters that can offer insights that i should look out for? I'm trying to do a ROI period stretching to 4 years. Upgrading of FC controller are out of the question in the 4 year period. As the system has to pay for itself in this 4 year period. Your feedback is very much appreciated. |
