Storage compression (was: Cost of storage calculator?)
In article .com,
wrote: Thanks Ralph... With the storewiz product they claim that management overhead is nil (I doubt this, but lets just say its true), then would such a technology (even if not from storewiz) be appropiate to invest it? So it is installed by elves, without any downtime by using Hermione's time-turner, configuration updates are done by angels while you sleep (my computer never sleeps, by the way, too many chocolate-covered espresso-beans in its youth), it never fails, and if it fails anyhow, the Storewiz field engineering people arrive an hour before the failure to hot-swap a spare in (they have the second sight)? Give me a break - intentional pun. I can attest to the fact that thus far, I've had no issue with StoreWiz's reliability... it actually isnt taking me too much time to manage it in my dev lab... almost none at all... OK, now manage it in a production setting, say in the data center of a bank or insurance company (think Chief Privacy Officer, think SEC regulation, think Sorbanes-Oxley). First step: Have your computer security people do a full audit that the compression gadget is secure enough. That includes checking key distribution, TCP/IP ports, password management, integration into the LDAP authentication infrastructure, and auditing all software upgrades. I'll stop right there, because one of your computer security experts (who run $120K per year salary alone) just spent a week on this new gadget. We haven't even started using the device yet, because the computer security people won't allow you to uncrate it until they have given it their blessing, and written the 30-page policy manual for how you shall manage it from a security point of view. I'm exaggerating here, but not very much. -- The address in the header is invalid for obvious reasons. Please reconstruct the address from the information below (look for _). Ralph Becker-Szendy |

Storage compression (was: Cost of storage calculator?)
I understand the points you are raising... they are very valid in our
environment... But those are true of any product we introduce Ralph... All new products we introduce into the production go through quite similar rigorous scruitiny and yes, they do cost a lot (LOT) of time... But it applies horizontally for all products... so we dont even compute that anymore into comparing different products... But once setup, it seems to be able to work silently... I do have a lot of issues with its ability to work on non textual (non office) type of data, but I want to see where this industry will go... and if I should invest in the technology now (assuming they fix all their nuances)... /l |

I dont want to buy something that is seen as non standard /l Unless they are using some wild-ass algorithm that no one's ever seen outside of their company compression has been standard in many environments since it was available. And even if something is non-standard, if it serves a need then it's worth it. ~F This thread is timely. I was at interop this week and met with StoreWiz. They provided me with their ROI calculator. We have about 200TB of data and grow at the rate of 20% a year. Plugging in my numbers into their calculator, here is what I got Start: 200TB of data Growth Rate: 20% Cost per terabyte to me: 12K just for hardware (fully loaded with NetApp) Assuming a 30% reduction in storage using StoreWiz compression hardware, I get a net savings of 1.2M in 2 years. The cost of the Storewiz appliance is 45K. Given that I only computed in hardware costs per terabyte (we typically spend more per terabyte than that if you factor in management, electricty and floor costs), I think this is a very good deal HTH |

When I spoke with them they could only front end a single filer at a time. And if you want redundancy you have two appliances per filer head. At 200TB of primary storage (non R class filers) you are looking at 3 filers minimum, more likely 4+. So if you have 4 filers, and want redundancy, you had to purchase 8 storewiz appliances. And this also assumes their calculator is correct for your specific data sets. ~F |

I currently have 200TB accross 6 filers.... and they seemed positive
that me that all our guys would need was just two storewiz appliances... one of them being for redundancy. The ROI calculator (which is a spreadsheet) seemed pretty basic. Email me if you want a copy of the spreadsheet. It basically shows how fast 200TB at 20% growth with 12K per TB would add up every year with and with out storewiz compressing at 30%. They also have a software tool that will accurately predict how well they can compress (which I will give a try next week). |

I am particulary interested in Snapvault and Snapmirror. The website says iSCSI and FC coming soon. I have sent them few emails and haven't received any response yet. -G |
