  • Storage basics
    drives will typically outlast SATA drives But SCSI is not cheap to implement and UltraSCSI drives UltraSCSI is the most advanced form of the standard and the most common today are therefore more expensive than their SATA cousins SATA is also said to be a simpler standard to implement which means cheaper drives although this comes with reliability issues On the upside however is a newish SATA feature called native command queuing NCQ that makes it possible to have several outstanding commands within a drive at the same time and therefore speed access Consensus suggests that SCSI is the best option for core storage tasks with SATA the better candidate for secondary storage roles where speed is important but constant heavy duty data wrangling is less likely to be required Squeezing extra speed out of either standard is very much a case of understanding where each can make a difference when faced with particular storage needs Network complications Complicating matters further is the choice of network over which to carry data and which can afford greater speed The complication comes from the fact that standards like Fibre Channel ATA FATA can let SATA drives connect to a Fibre Channel network Fibre Channel is of course a networking protocol and was initially developed as the successor to HIPPI a 1980s favourite for machine to machine networks that screamed along at then amazing speeds of 800Mbit s Fibre Channel aimed to exceed that speed and was later adapted as a way to connect SCSI disks in recognition of the need for high speed data exchange between storage arrays with its 4 Gbp s once a delightfully speedy alternative Fibre Channel can now connect to SATA or SCSI drives with few worries about the kind of disk at the other end It is fast reliable and widely used It remains however a somewhat different network protocol With Ethernet the world s dominant networking protocol many organisations wonder if it makes sense to acquire Fibre Channel and the equipment and skills needed to operate it especially now that Ethernet has reached 10Gbp s and there are storage devices more than happy to take advantage of that speed Organisations looking for storage speed are now therefore conducting interesting trade offs of speed vs reliability vs cost of acquisition vs cost of ownership Less is more Another issue affecting the search for speed is the growing array of tools techniques and technologies that seek to reduce the amount of data that must be carried with data de duplication to the fore and offering users a chance to simply store less data Most approaches to this issue seek to shrink the size of every file ever created the better to speed its passage over networks disks and buses alike Few vendors approaches to this problem are the same and all therefore deserve individual consideration And that approach of careful assessment to ensure that storage systems meet your need for speed and general utility is what underpins the

  • New iSCSI SAN/NAS box touts better performance
    the system s throughput over serial bus connections like PCI Express which is used in the HP and Dell systems Agami is claiming single stream throughput of around 100 megabytes per second MBps which is similar to its counterparts but claims aggregate throughput up to 300 MBps The box can trunk ports to allow a single host the entire aggregate throughput if necessary According to Tony Asaro analyst with the Enterprise Strategy Group ESG the product has been tested in ESG s labs and showed performance numbers close to Agami s claims The AIS system achieved 106 MBps of throughput over a single Gigabit Ethernet GigE interface he wrote to SearchStorage com in an email Aggregate performance scaled in a near linear fashion to 226 MBps HP s AiO claims CIFS throughput of around 120 MBps but is cagier when it comes to its overall iSCSI performance You can t just multiply the single stream throughput to get the aggregate with iSCSI You can do NIC teaming MPIO TOE cards and it also depends on the size of the frames and networking setup in the customer environment said Brad Parks worldwide product marketing manager for AiO storage Dell s box meanwhile can hit 420 MBps aggregate throughput but ports can only be trunked on a pure NAS system For iSCSI solutions we utilize the Microsoft iSCSI Initiator and MPIO technology which recommends the use of MPIO for communicating data down multiple physical paths wrote Scott Sinclair marketing product manager for NAS at Dell to SearchStorage com in an email Finally the Agami system is based on a Linux kernel rather than the Windows OS which could appeal to some administrators who feel Windows is a less reliable operating system The AIS1006 also has battery backed cache that allows it to avoid the Windows disk check after a crash According to Asaro though Agami s product is primarily being marketed to small and midsized businesses SMB HP and Dell not only have better name recognition in that market than Agami but they can sell them other stuff besides storage SMB users also tend to be loyal to Windows and HP and Dell s offerings are better integrated with some Microsoft applications like Active Directory thanks to those companies preexisting relationships with Microsoft HP is also offering more software features to coax SMB users toward networked storage including a wizard designed specifically for migrating data from DAS to NAS that can be used with the AiO Finally low end boxes like the AiO are not being sold into performance sensitive environments Agami will probably also never beat the big players on price Currently it s selling the AIS1006 only through its Web site in order to avoid having to boost the price to preserve margins for both itself and channel partners In the SMB space it s almost impossible to get more than a 30 margin Asaro said HP and Dell can live comfortably there but a pure storage player like Agami

  • LeftHand refreshes iSCSI SAN software
